# 24 IQ Test Interview Questions and Answers

## Introduction:

Are you gearing up for an IQ test interview? Whether you are an experienced professional or a fresher, preparing for common IQ test questions can make a significant difference in your performance. In this article, we'll explore 24 common IQ test interview questions and provide detailed answers to help you succeed in your interview.

## Role and Responsibility of an IQ Test Candidate:

The role of an IQ test candidate involves demonstrating your cognitive abilities, problem-solving skills, and logical thinking under time constraints. Employers use IQ tests to assess your aptitude for various tasks, so it's essential to be well-prepared for these assessments.

## 1. What is the next number in the sequence: 2, 4, 8, 16, ?

The interviewer wants to evaluate your pattern recognition and mathematical reasoning skills.

How to answer: To answer this question correctly, you need to recognize that each number in the sequence is doubling the previous one. So, the next number would be 32.

Example Answer: "The next number in the sequence is 32. Each number is double the previous one, so 16 doubled is 32."

## 2. Which word does not belong in the following list: apple, orange, banana, cherry, table?

The interviewer is assessing your ability to identify patterns and categorize items logically.

How to answer: The word 'table' does not belong in the list because it is a piece of furniture, while the other items are fruits.

Example Answer: "The word 'table' does not belong in the list because it is not a fruit, while the others are all fruits."

## 3. If three cats catch three mice in three minutes, how many cats are needed to catch 100 mice in 100 minutes?

This question tests your ability to solve simple mathematical problems and think logically.

How to answer: Only three cats are needed because the number of cats does not affect the number of mice caught when the time and conditions remain the same.

Example Answer: "You would still only need three cats to catch 100 mice in 100 minutes. The number of cats doesn't change the rate at which the mice are caught."

## 4. If you rearrange the letters "CIFAIPC," you would get a common English word. What is it?

The interviewer is testing your anagram-solving skills and vocabulary.

How to answer: Rearranging the letters in "CIFAIPC" will give you the word "PACIFIC."

Example Answer: "The common English word formed by rearranging 'CIFAIPC' is 'PACIFIC.'

## 5. A bat and a ball cost \$1.10 in total. The bat costs \$1 more than the ball. How much does the ball cost?

This question assesses your ability to solve simple math problems and think critically.

How to answer: The ball costs \$0.05. If the ball costs \$0.05, the bat would cost \$1.05, making the total \$1.10.

Example Answer: "The ball costs \$0.05. The bat costs \$1.05, and together they add up to \$1.10."

## 6. If a plane crashes on the border of the U.S. and Canada, where would you bury the survivors?

This question tests your ability to think critically and not take questions too literally.

How to answer: You wouldn't bury the survivors; you would help them and provide medical care and support.

Example Answer: "You wouldn't bury the survivors; you'd provide them with medical care, support, and assistance."

## 7. If you have three apples and you take away two, how many apples do you have?

This question checks your ability to think logically and consider the situation carefully.
