2019 Tips for choose best School for your Child

One of the great decisions we will make as parents in the first years of our children's lives and that can make a big difference in their future is deciding where they will spend their academic life.

Before the child is born, the choice of the school he will attend is a topic of concern for many families. The most important thing is to consider what values ​​interest you as a mother . Thus, you will not be afraid of making a mistake.

There are families for whom discipline and success are above whether the student feels good or not in a school. For others, on the other hand, humane treatment is paramount.

Considerations to choose the best school for your children

Do it as soon as possible:
Do not wait until the child has five years to decide which school you want to take him to. Even if you are not going to do the application, at least go thinking about the type of school.

There are public/gvt, private schools, free schools and there are also people who decide to educate at home by private hired teacher but it is not easy of middle or lower income family.

Public or private school:
Not everyone can consider the monthly payment of the school.

Going to a public school is in many cases a necessity. In other cases, it may be the best educational option, if you live in a good school district.

Choosing a private school because socially is better seen than a public one is a mistake we should not make.

An integrating school:
A philosophy of unification is essential. Our children live in a multicultural country and this is what their school should be like.

Although the websites of the schools transmit that they are great places, the best thing is to ask other parents.

When choosing an educational center, ask yourself if there is diversity in terms of race, ethnicity, religion, values and any other factor that is important to you.

The academic level:
We have to find out what is the educational style of the school.

Go to the open days that serve to show the school to parents. Ask all the questions you have, express your doubts and ask them to inform you about the methods they use and at what level they are with respect to other schools in your city. Ask if there are support classes. Psychologists and teachers in continuous training are an important educational pillar.

Number of students and facilities:
The number of students per class is very important so that children can be attended to normally. An overly full class is a source of stress for children and teachers.

The facilities that the school has are another factor to take into account: number of buildings, age of the same and good equipment.

The humane treatment:
Keep in mind that the human treatment of teachers towards students is equal or more important than the educational system. When your children grow up, their level of academic enthusiasm could be directly related to the personal treatment of the teachers who teach each subject. Inquire at the school and try to show that the teaching staff is trained to transmit enthusiasm and desire to learn.

That the school is close to home
Distances in the United States can be very large and we are used to it. But perhaps we should consider if the best thing for our children is to spend each day around two hours in the car in addition to school hours and thus complete a day of "work" as if they were adults.

A school near our home makes it easier for children to relate to each other outside of it and above all it will make them less tired and have more time to play or take a special class that they may have chosen.

Tips to get a job that allows you to stay in your own home

Working from home has in recent years become a real possibility for many workers. Many factors have influenced the increase of workers at home: sometimes for reasons of saving time in traffic, other times for lack of space in the office, and other times by own choice.

The space you must create to work at home. - First of all, you should have a space at home reserved for work and even for the job search.

A separate room with a desk would be ideal. If the lack of space does not allow you to have an office in a dedicated room, you should at least assign a sacred space inside a room where nobody bothers you for long periods of time. Access to computer, internet, and telephone are the essential tools for this place.

Search by internet: Luckily, there are already several websites that offer jobs to stay at home. As an initial step, I would recommend you visit the dedicated page ( where you can find all the necessary information about the job search from home.

Separate the fraud of the real offers: With the increase in popularity of work from home, a new wave of online fraud has arrived. Winning a lot of money with little effort and without moving from home have become the ideal hook for fraudulent websites offering jobs from home.

Apply common sense to these offers- if it sounds too good to be true, it's probably fraud. Other tips to help you determine the veracity of the offer include:

  • Never pay to put your resume online or to receive job offers
  • Never give your bank account number to job seekers

  • Ask to speak with other employees of the company to obtain their points of view and verify the veracity of the offer
  • When using job vacancies such as Monster or Career Guide , use keywords such as freelance, home based, work from home, or work at home to narrow down the list of results.

Strategies to manage your time: the ideal balance. When people hear the words "work from home" almost always associated with freedom, flexibility of schedule and all the time in the world to enjoy family / friends. The reality is that for many people it is more complicated to produce results in an environment where there are no established rules. Everything depends on your personality. Without a doubt, it is advisable to create your own schedule to keep you productive. Separate the professional's family time. In any case, the use of calendars and a place without distractions are essential recommendations for any worker at home. Follow the following tips to maintain an ideal balance:

  • When the schedule you have marked for work ends, disconnect from work and attend to your family / friends
  • Ignore your emails during non-business hours
  • Assign blocks of time to check your email and do not let yourself be interrupted by every email that enters your inbox
  • Limit the time spent reading news and social networks
  • Work without distractions and without getting up during periods of 45 minutes to an hour.
  • Every hour, rest for a period between 10 and 15 minutes to refresh the mind
  • Keep a daily plan about what you are going to achieve that day and review it at the end of each day
  • Focus on one thing alone. Forget about the idea of ​​multitasking

Works that can be done without leaving your home: Luckily, if your dream is to be able to work from the comfort of your home, there are many jobs that do not require daily visits to the office. Jobs as analysts, graphic designers, accountants, writers, and many others have the flexibility to be able to play them from anywhere. If, on the contrary, your work requires visits from clients or continuous meetings with colleagues, maybe you can only do part of the work at home.

The future, technology, and the little need to leave home: Many are those who predict that the near future most jobs can be played at home. Technological advances in communication and robotics fields even make it possible for doctors to perform surgeries from their own home. Despite what the future holds for us, it is obvious that technology allows us to perform more and more tasks without having to access the tools that only existed in the buildings of companies. For example, with advances in mobile telephony, today you can answer all your emails from your phone, make video conferences, use apps for a multitude of tasks, and even read this article.

What are your skills? Interview Question Best Answers

Questions about your skills are one of the most common in any job interview. In fact, many of the interviewers focus on discovering how you, the candidate for employment, with your skills and competencies, can benefit the company. To answer them, we must mix the necessary confidence to "sell ourselves" with enough humility to not be arrogant.

What relevant experience do you have for this job? You have to demonstrate readiness to be able to answer this type of question.

The important thing is connecting the details of the job announcement with your work experience. The more details you use, the better. And do not try to exaggerate (or lie) about your experience since it is easy to call one of your references to corroborate data.

How would you describe yourself? Although it is an obvious and easy to answer question, it really is not. If you have not stopped to think about this question before, you will appear to be poorly prepared for the tasks demanded by the job. Apart from honesty, the important thing is to find the ideal connection between you and the work in question. If you are a creative person (among many other things) and you are a candidate for a creative position, highlight that facet clearly.

How would you describe your work style? This question aims to discover if you are slow at work, very fast, or if you maintain a constant speed in your work.
Not always the fastest will get the job. Many employers prefer candidates who work at a constant speed and who meet project dates. Elaborate a bit about your ability to manage your time and how you do to carry several projects at the same time.

How do you deal with stress at work? Stress has become a component of every job and interviewers want to know how you handle stress at a professional level.

Before the interview, do an auto-analysis to determine your reactions to stress. There are many answers you can give. Some positives include: "I get along well in stressful situations and use that energy to raise my results." Another answer could be: "I usually accumulate stress during the workday but I burn it all in the gym at night to get cool back to work the next morning". Whatever the answer, try to include some specific example of how you have handled stress in the past.

What motivates you? Definitely, there is no simple answer to this question. But you must be prepared to answer it. You can emphasize your motivations and specific examples. Many people are motivated simply by money, others by a positive work environment, and others by the possibility of learning new things. Be honest and specific in your answer.

What kind of work environment do you prefer? The interviewer will try to discover if there is a connection between your style and the workplace. If your ideal environment is relaxed with the freedom of a flexible schedule, present that style in a positive way with a focus on increasing productivity.

  Unless you intend to radically change your style, it would be a good idea to discover if there really is a connection between your style and the company's before you start working. Example of response: "I develop better in a rigid environment with established schedules and with well-established objectives, my work style is organized, meticulous, and detailed, I like to have everything well planned".

What are your passions? Prepare to share some of your passions. You do not have to enter into very personal passions but you can find those that can be translated into professional situations. For example, "I am passionate about helping others, and on Saturday mornings I am a volunteer with a group that helps disadvantaged people in our community, and I believe that this work also has a component that helps others.

Thanks to the services that this company provides, many people can ....".

How can you contribute to this company? The company has some ideas about what the candidate should contribute (specified in the job announcement) and you may have some other ideas on how to contribute to the company. This is the time to present some of your ideas to demonstrate not only your qualifications but also an interest in the future of the company.

Why do you want to work here? Honestly, he finds something positive about the job that makes him attractive. Try to look beyond the salary.

What challenges do you like to find in a job? All work presents challenges. Some more bearable than others. In any case, motivated people often find these challenges an extra motivation. What challenges motivate you the most? Present them in a positive way so that the company has a better idea of ​​your fit in the work.

Why are you the ideal candidate for this job? Here you have to sell as the best "product". The company received a thousand resumes for the position and you are among the three finalists. Do not underestimate yourself and honestly present the reason why you think you are the ideal candidate. Joining the job announcement with your specific skills will increase your chances of becoming the ideal candidate.

SSIS Interview Questions And Answers for beginner and experienced

  1. What is MSBI ?

        MSBI stands for Microsoft Business Intelligence MSBI (Microsoft Business Intelligence) is one of the ETL tool related to the database side. MSBI is composed of tools which helps in providing best solutions for Business Intelligence and Data Mining Queries.

    MSBI is divided into 3 categories:-

  • SSIS – SQL Server Integration Services – Integration tool.
  • SSAS – SQL Server Analytical Services -Analysis tool.
  • SSRS – SQL Server Reporting Services – Reporting tool

  1. SSIS– This tool is used for the integration like duping the data from one database to another like from Oracle to SQL Server or from Excel to SQL Server etc.
    This tool is also used for bulk transactions in the database like inserting lac's of records at once. We can create the integration services modules which will do the job foe us.
  2. SSAS– This tool is used to analyse the performance of the SQL server in terms of load balancing, heavy data, transaction etc. So it is more or less related to administration of the SQL Server using this tool. This is very powerful tool and through this we can analyse the data inserting in to the database like how many transactions happens in a second etc.
  3. SSRS– This tool is related to the generation of report. This is very efficient tool as it is platform independent. We can generate the report using this tool and can use in any type of applications. Now a days this is very popular in the market.

Q. What is SSIS variable?

Variables store values that a SQL Server Integration Services package and its containers, tasks, and event handlers can use at run time.

In SSIS two variables are defined
  • Global variables:- A global variable is available to all tasks across the entire job. 
  • Task level variables: - Variables created in tasks are only available within that task.

Q. What is SSIS Control flow?

SSIS control flow allows you to program graphically how the tasks will run by using the logical connectors between tasks.

There are three basic logical connectors that you can use:
  • Success 
  • Failure 
  • Complete

Q. What is precedence constraint?

In SSIS, tasks are linked by precedence constraints. A task will only execute if the condition that is set by the precedence constraint preceding the task is met.

The control flow in a SQL Server Integration Services (SSIS) package defines the workflow for that package. Not only does the control flow determine the order in which executable will run, the control flow also determines under what conditions they’re executed.

  • Success: The precedence executable must run successfully for the constrained executable to run. This is the default value. The precedence constraint is set to green when the Success option is selected. 
  • Failure: The precedence executable must fail for the constrained executable to run. The precedence constraint is set to red when the Failure option is selected. 
  • Completion: The constrained executable will run after the precedence executable runs, whether the precedence executable runs successfully or whether it fails. The precedence constraint is set to blue when the Completion option is selected.

Q. Defined the different type of containers in SSIS packages

In SSIS there are three type of Container:-


1. Sequence Container: - Sequence container defines the control flow that is subset of package control flow. Sequence containers group the package into multiple separate control flows, each containing one or more tasks and containers that run within the overall package control flow.

Advantage: -

· Disable the property of sequence container instead of on the individual tasks.

· Change the property of sequence container instead of on the individual tasks.

· Providing scope for variables that a group of related tasks and containers use.

2. For Loop container: - It’s define the repeated control flow in a package. It’s working like loop in programming languages. In each repeated loop for each loop evaluate the expression until the expression is false. Example, you need to update records 5 times, you can place the task that updates the records inside this for loop container and specifies 5 as the end of the loops by using the for loop container.


For loop Properties:-

  • InitExpression:- Optionally, provide an expression that initializes values used by the loop. 
  • EvalExpression:- Provide an expression to evaluate whether the loop should stop or continue. 
  • AssignExpression:- Optionally, provide an expression that changes a condition each time that the loop repeats. 
  • Name:- Provide a unique name for the For Loop container. This name is used as the label in the task icon. 
  • Description:- Provide a description of the For Loop container. 

3. Foreach loop container

It’s defines a repeating control flow in a package. Foreach loop implementation is similar as programming languages. In a package, looping is enabled by using a Foreach enumerator. The Foreach Loop container repeats the control flow for each member of a specified enumerator.

SSIS provides these following enumerator types:

  • ForEach File Enumerator 
  • Foreach Item Enumerator 
  • Foreach ADO Enumerator 
  • Foreach ADO.NET Schema Rowset Enumerator 
  • Foreach From Variable Enumerator 
  • Foreach NodeList Enumerator 
  • Foreach SMO Enumerator

Do you have an interview with them and do not know where to start? Today is your lucky day. I want to confess some of the best kept secrets to overcome your next interview at McDonald's.

Before going to the interview, learn well about the company, because as it is very recognized and is very integrated into our lives it is easy for everyone to say the same things about it, so take a step further and take advantage of this advantage.

Find something that you can say that is positive, original, different ... That makes you stand out!

Well dressed and with good presence: Do not go formal , but with a good image. It is possible to end up working facing the direct public (cashier, store assistant) or indirectly (kitchen, manager).
Come early: If you arrive late, they will think that you have no interest and that you are a disorganized person, but if you arrive very soon, you will seem impatient, restless, anxious ... Ideally, you should arrive between 10 and 5 minutes early.
Pay attention to the smells! Be well groomed, do not get into a race because you are late before entering. You will throw everything away! Avoid smoking and drinking coffee before entering.

Analyze how they work at Mcdonald's: In front of the public, as a team, under pressure, in turns ... If you want to work here, be able to work according to your philosophy and work rate .

Highlight what skills you have that fit your operation.

Now, we begin! These are the most common questions in the selection process:

I want to work at Mcdonald's because it is an international company that offers me the possibility to train and be part of a multidisciplinary team. In addition, it gives me security the fact of being a great company, not only at work level, but also in quality and management of all processes.

Tell him to take charge. If you can tell a manager better than better, but if not, to a partner. In any case, you will have to tell the person in charge, even if it is later.

No, unless it is absolutely essential to solve a problem.

Serving food has given me extensive experience facing the public and solving problems with customers on a daily basis. In addition, this experience will make me more willing to take care of the store when necessary.

The questions of the weaknesses formulated in another way ... "I am too demanding and that makes me add more pressure than necessary ..."

How Prepare for face 5 most common types of interview questions

Prepare for the questions that recruiters will ask you and give an effective response.
From the interview we expect a professional conversation, focused mainly on our skills and achievements, however, sometimes the recruiter will look for 'something else' about us with questions that may not be directly related to employment.

For many candidates some interview questions do not have a logical reason, they can even be absurd or uncomfortable, so we must be prepared and anticipate to respond with intelligence.

Prepare to face the 5 most common types of interview questions:
1. Open: They are general questions that seek to flow the dialogue between the interviewer and the candidate, allow the person a broad response. With them your fluency, communication skills and coherence will be evaluated.

Example: Tell me about yourself, why were you interested in the vacancy? Why did you decide to study (insert career)? What do you like most about your work?

Tip: It is possible to prepare in advance to answer these types of questions, since they are very common. It is important to find a balance in our speech to express ourselves with ease without giving very long answers. Concentrate on the most meaningful and relevant information.

2. Fitness: Its objective is to evaluate if the candidate has the necessary knowledge to perform the job. Depending on the vacancy, the recruiter will inquire about the candidate's experience and the competencies he or she has.

Example: What were the main functions you performed in your previous job? , Tell me what knowledge and skills prepare you for the position, I see that you have advanced knowledge in (insert skill / knowledge) in what kind of activities have you applied the last 3 years?

Tip: Probably a lot of this information is contained in your Curriculum, however the recruiter will want to have a bigger picture. Using specific examples can help you clearly show why you meet the expectations of the position.

3. Behavior: When making a contract, it is not only important that the candidate can do the job. The behavioral questions seek to find out what the person's behavioral profile is, to assess whether they can successfully integrate into the work team.

Example: How do you handle stress ?, Give me an example in your work life in which you have shown integrity, Tell me about a time when you made a mistake in your work, how did you solve it?

Tip: Anticipate this type of questions by analyzing how your behavior at work is, what are your strengths and what are your areas of opportunity. Prepare yourself with clear examples of scenarios typical of the work environment such as stress, pressure, decision making, labor conflicts, etc.

4. Situational: Once the interviewer analyzes your behavior in the past you can resort to situational questions to get an idea of ​​what your future behaviors will be.

Example: How do you respond to pressure? Imagine that you have X problem at work, how would you solve it? What would you do if your boss delivers a report with erroneous figures in a work meeting?

Tip: For situational questions there is not a single correct answer, it will reveal our ability to solve problems and adapt to different situations. A good practice is to think about a similar experience that you have lived and talk about how you used your skills to face it.

5. Capciosas: It may seem absurd or incoherent questions, but depending on the recruiter, the company and the position, you may have to answer questions that seem to leave the work context. Its purpose is to move the candidate a little away from standard questions and subject him to a mental challenge that reveals a little more about his personality.

Example: If you could be an animal, what would you be? What color is there more objects in your bedroom? What would you prefer? Being the number 1 employee but hated by your colleagues or number 15 but appreciated by all?

Tip: With these questions the recruiter expects an honest and spontaneous answer, remember that there are no correct answers, since they are linked to your personality.

* Inappropriate Questions
It is common for candidates to face misplaced questions, which can be discriminatory and offensive. For example, are you pregnant? What contraceptive method do you use? What is your sexual orientation? Why are not you married? Are you religious / religious?

Machine Learning Interview Questions Answers: Scope of Machine Learning

Many of us believe that machine learning is a very futuristic thing. However, it is increasingly present in our lives, whether when a Google computer plays an incredible game of Go, or when Gmail generates automatic responses. While all this sounds exciting, many of us continue to wonder what machine learning exactly consists of, why it is so important or why identifying a dog in a photo is not as simple as it seems. In order to analyze all this, we have met with Maya Gupta, a researcher at Google in this field.

Let's start with the simplest: what exactly is machine learning?
It is the process of machine learning that takes a set of examples, discovers the patterns behind them and uses them to make predictions about new examples.

Think, for example, about movie recommendations. Let's suppose that a billion people tell us their ten favorite movies. That would be the set of examples that the computer can use to discover which movies are common among that group of people. Next, the computer elaborates patterns to explain those examples, such as "People who like horror movies do not like romantic ones, but they do like movies in which the same actors appear". Therefore, if you tell the computer that you like The Shining of Jack Nicholson, you can deduce if you also like romantic comedy.

We understand it or almost. However, how does this translate into practice?
In practice, the patterns that the machine learns can be very complex and difficult to explain with words. Let's use Google Photos as an example, which allows you to search your photos for pictures of dogs. How does Google do it? Well, first, we use a set of examples of photos labeled "dog" (thanks to the Internet). We also use a set of photos labeled "cat", as well as photos with millions of different labels, but I will not list them all here.

Next, the computer looks for patterns of pixels and patterns of colors that help you to find out if it is a cat, a dog or anything else. First, he makes a random estimate of the patterns that might be adequate to identify dogs. Then examine an example of an image of a dog and see if its patterns fit correctly. If you check that a cat is mistakenly called a cat, make some adjustments to the patterns used. Then examine the image of a cat and refine its patterns to try to get the most accurate. This process is repeated about a billion times: it examines an example and, if the pattern is not correct, it changes it to improve the result of it.

In the end, the patterns constitute a model of machine learning, as if it were a deep neural network that can (almost) correctly identify dogs, cats, firemen and many other things.

That sounds very futuristic. What other Google products currently use machine learning?
Google is using machine learning in many new projects, such as Google Translate, which can take a picture of a signage sign or restaurant menu in a language, discover the words and language that appear in the photo, and translate them by magic and in real time to your language.

You can also send almost any voice message to Google Translate and speech recognition can be processed by machine learning. Speech recognition technology is used in other Google products, for example, to make voice queries in the Google application or to search for videos more easily on YouTube.

Machine learning is the same as artificial intelligence?
Although in reality the meaning of these concepts can vary according to people, artificial intelligence (AI) is basically a broad term that refers to software that tries to solve problems that are simple for humans, such as describing what happens in an image. One of the most incredible things that humans do with ease is to learn from the examples. This is what machine learning programs are trying to do: teaching computers how to learn from examples.

The best thing is that when we discovered how to develop these software, we can expand this knowledge to handle data very quickly and solve really complex problems such as, for example, play as an expert to the Go, tell the way to all users so Simultaneously, optimize energy consumption nationwide and, my favorite, find the best results in the Google search engine.

So, why is Google now giving so much importance to machine learning?
Machine learning is not something new, since it goes back to the eighteenth century statistics, but it is true that lately it is booming and this is due to three reasons that I will explain below.

The first one is that we need an immense amount of examples to teach computers how to make good predictions, even about things that you and I consider easy (like finding a dog in a photo). With all the activity on the Internet, we now have a broader source of examples that computers can use. For example, there are now millions of pictures of dogs with the "dog" tag on websites around the world and in all languages.

But it is not enough to have many examples. You can not simply show a bunch of dog photos to a webcam and expect him to learn everything; the computer needs a learning program. In fact, lately the sector (and also Google) has made important advances in terms of the complexity and power that these learning programs can have.

However, our programs are still not perfect and computers are still not very intelligent, so we have to see many examples numerous times to change the digital controls and get accurate results. Although this requires enormous processing capacity, new advances in software and hardware have also made this possible.

Is there something that computers can not do today but what can they do in the future thanks to machine learning?
Until now, the voice recognition tried to detect only ten different digits when you said your credit card number by phone. Voice recognition has achieved incredible advances in the last five years with the use of machine learning, and now we can use it to search Google and every time more quickly.

I think machine learning can also help us improve our appearance. I do not know about you, but I hate to try on clothes. If I find a jeans brand that suits me, I buy five. Well, machine learning can convert examples of brands that we feel good into recommendations of other clothes that could equally well fit. This is out of Google's reach, but I hope someone is investigating it.

What will machine learning be like in ten years?
The sector is currently working to achieve faster learning from fewer examples. One way to address this (something that Google is emphasizing) is to provide our machines with more common sense, what in the sector is called "regularization".

What is common sense for a machine?
In general, it means that if an example changes only a little, the machine should not omit it. That is, a picture of a dog wearing a cowboy hat is still a dog.

We impose this kind of common sense when we get that machine learning is able to obviate small and insignificant changes, like a cowboy hat. Although this seems easy to say, if we make a mistake, it is possible that a machine does not detect important changes well. It is about reaching a balance and we are still working to achieve it.

For you, what is the most exciting thing about machine learning? What motivates you to work with him?
I grew up in Seattle, where we learned a lot about the first explorers in the Western United States, such as Lewis and Clark. Machine learning has that same spirit of exploration, since we discover things for the first time and try to trace a path towards a great future.

If you could put a slogan to Google's machine learning, what would it be?
If you do not get it first, try a billion times more.
