The 8 Tough Brain Teaser Interview Questions and Answers

As a job seeker, it’s important to be prepared for any questions that may come your way during an interview, including tough brain teasers. These questions are designed to assess your problem-solving abilities and critical thinking skills. Here are eight examples of tough brain teaser interview questions and answers that you can use to help you prepare for your next job interview:

Question 1: Example Question and Answer

Q: How many golf balls can fit in a school bus?

A: To answer this question, you need to make some assumptions. Let’s assume the school bus is 40 feet long, 8 feet wide, and 6 feet high. That means it has a volume of 1,920 cubic feet. Now, let’s assume a golf ball is 1.68 inches in diameter. That means each golf ball has a volume of about 2.65 cubic inches. To fill the entire school bus with golf balls, we need to convert the volume of the school bus to cubic inches and then divide by the volume of a single golf ball.

  1. Convert school bus volume to cubic inches:

40 ft x 12 in/ft = 480 in (length) 8 ft x 12 in/ft = 96 in (width) 6 ft x 12 in/ft = 72 in (height) 480 in x 96 in x 72 in = 331,776 cubic inches

  1. Divide school bus volume by golf ball volume:

331,776 cubic inches ÷ 2.65 cubic inches per golf ball = 125,233 golf balls

So, the answer is approximately 125,233 golf balls can fit in a school bus.

Question 2: Example Question and Answer

Q: How would you design a spice rack for blind people?

A: This question is designed to assess your creativity and problem-solving abilities. A possible answer might include:

Question 3: Example Question and Answer

Q: You are standing in front of three light switches. One of them controls a light bulb inside a closed room. You cannot see into the room. You can only open the door once, and after that, you cannot touch the switches. How do you figure out which switch controls the light bulb?

A: To solve this brain teaser, you need to follow a specific set of steps:

  1. Turn on one of the switches and leave it on for a few minutes.
  2. Turn off that switch and turn on another switch.
  3. If the light bulb is on, then you know that the switch you just turned on controls the light bulb. If the light bulb is off but warm to the touch, then you know that the switch you initially turned on and then turned off controls the light bulb. Finally, if the light bulb is off and cool to the touch, then the remaining switch controls the light bulb.

Question 4: Example Question and Answer

Q: You have a 3-gallon jug and a 5-gallon jug. How can you measure exactly 4 gallons of water using only these two jugs?

A: Here’s a step-by-step solution:

Fill the 5-gallon jug to its maximum capacity. Pour the 5 gallons of water from the 5-gallon jug into the 3-gallon jug, which will leave 2 gallons of water in the 5-gallon jug. Empty the 3-gallon jug. Pour the 2 gallons of water from the 5-gallon jug into the empty 3-gallon jug. Fill the 5-gallon jug to its maximum capacity again. Pour enough water from the 5-gallon jug into the 3-gallon jug until the 3-gallon jug is full. This will leave 4 gallons of water in the 5-gallon jug.

Now you have exactly 4 gallons of water in the 5-gallon jug.

Question 5: Example Question and Answer

Q: How many trailing zeros are there in the number 100 factorial (100!)?

A: To determine the number of trailing zeros in 100!, you need to identify the number of factors of 5 since multiples of 10 (which have one trailing zero) are created by the combination of factors of 2 and 5.

Counting the number of multiples of 5 less than or equal to 100 gives you 20. However, there are multiples of 5 squared (25), multiples of 5 cubed (125), and so on. So, you need to consider the additional multiples of 5^2, 5^3, and so on that divide 100.

Dividing 100 by 5^2 gives you 4, and there are no multiples of 5^3 or higher within the range of 1 to 100. Therefore, the total number of trailing zeros in 100! is 20 + 4 = 24.

Question 6: Example Question and Answer

Q: How many squares are there on a chessboard?

A: To count the number of squares on a chessboard, you need to consider squares of different sizes. Start by counting the 64 individual squares (1×1). Then, count the 49 squares that are formed by combining four individual squares (2×2). Continue this process for squares of size 3×3, 4×4, and so on until you reach the largest square, which is the entire chessboard (8×8).

The total number of squares on a chessboard is the sum of all these counts:

1×1 squares: 64 2×2 squares: 49 3×3 squares: 36 4×4 squares: 25 5×5 squares: 16 6×6 squares: 9 7×7 squares: 4 8×8 squares: 1

Adding these counts together, you get a total of 204 squares on a chessboard.

Behavioral Questions vs. Brain Teaser Questions

A. Definition and Differences between Behavioral and Brain Teaser Questions

During job interviews, employers often ask job seekers a variety of questions to assess their problem-solving, critical thinking, and communication skills. Two types of questions that you may encounter during a job interview are behavioral and brain teaser questions.

Behavioral Questions: Behavioral questions inquire about how you have handled previous work situations or challenges. These questions are designed to allow the interviewer to understand your past work experiences, your response to various situations, and your attitude towards work. Behavioral questions require you to provide specific examples of how you have handled specific work scenarios in the past.

Brain Teaser Questions: Brain teaser questions are designed to assess your thought process, problem-solving capabilities, and creativity. These types of questions do not necessarily have a right or wrong answer. Typically, brain teaser questions are seemingly unrelated to the job or industry and may be puzzles, riddles, or other types of mind-bending challenges that rely on logic and critical thinking to solve.

The fundamental difference between behavioral and brain teaser questions is that behavioral questions look at how you have responded to situations in the past, while brain teaser questions assess your ability to think on your feet and solve unfamiliar problems quickly.

B. How to Prepare for Behavioral and Brain Teaser Questions

The best way to prepare for behavioral and brain teaser questions is to practice. Try to anticipate which types of questions may be asked and prepare specific examples to share during the interview.

For behavioral questions, review the job description and requirements before the interview. Then, think of specific examples that demonstrate how you have handled similar situations in the past. Make sure to use the STAR technique (Situation, Task, Action, Result) when answering behavioral questions to showcase your problem-solving skills effectively.

When it comes to brain teaser questions, the best way to prepare is by working on logic puzzles, brainteasers, and riddles. You can find plenty of resources online or in books to help you practice. Work on puzzles that stretch your mind and challenge you to expand your thinking.

Here, we will explore how hiring managers use brain teaser questions, the benefits of using them, and the limitations that should be considered.

A. How Hiring Managers Use Brain Teaser Questions

Hiring managers use brain teaser questions to get a sense of a candidate’s ability to think on their feet, approach problems creatively, and work through challenging situations. These types of questions often require the candidate to use logic, reasoning, and unconventional thinking to come up with a solution.

Some hiring managers use brain teasers as a way to gauge a candidate’s personality and how they handle pressure. These questions can reveal a lot about how a candidate works under stress, their communication skills, and how they adapt to change.

B. The Benefits of Using Brain Teaser Questions

There are several benefits to using brain teaser questions in the hiring process. First and foremost, they allow hiring managers to quickly assess a candidate’s critical thinking skills, which are essential for success in many roles.

Brain teasers also help hiring managers get a sense of a candidate’s personality and how well they may fit into the company culture. By asking questions that require unconventional thinking and problem-solving, hiring managers can get a sense of how a candidate approaches challenges and whether they are a good fit for the team.

C. The Limitations of Brain Teaser Questions

While brain teaser questions can be a useful tool in the hiring process, it is important to recognize their limitations. First and foremost, they should not be the sole criteria on which a candidate is evaluated.

It is also important to recognize that brain teaser questions may not accurately reflect a candidate’s ability to perform the specific job they are applying for. While these questions can be useful in assessing critical thinking and problem-solving skills, they may not be relevant to the day-to-day tasks of the job.

Finally, it is important to ensure that brain teaser questions are fair and not biased against certain candidates. Questions should be designed to challenge all candidates equally, regardless of their background or experience.

Brain teaser questions can be a useful tool in the hiring process, allowing hiring managers to quickly assess a candidate’s critical thinking skills and personality. However, it is important to recognize their limitations and ensure they are used fairly and effectively.

The Impact of Brain Teaser Questions on Job Performance

Incorporating brain teaser questions during the hiring process has become increasingly popular as hiring managers aim to assess a candidate’s ability to think critically under pressure. However, there is a debate on whether brain teasers accurately predict job performance.

A. The Relationship between Brain Teaser Performance and Job Performance

Some studies suggest that there is a positive correlation between brain teaser performance and job performance. Candidates who score well on brain teasers tend to perform better on the job. This is because brain teasers test a candidate’s ability to think logically, creatively and make sound decisions when faced with complex problems.

B. How Hiring Managers Evaluate Brain Teaser Performance

Hiring managers evaluate brain teaser performance in different ways. Some use it as a primary factor in deciding whether to hire a candidate, while others use it as one of many factors to evaluate a candidate. They assess a candidate’s performance by examining how quickly and efficiently they answer the questions, their thought processes, and the accuracy of their answers.

C. The Potential Risks of Overemphasizing Brain Teaser Performance

While brain teasers can be an effective tool for evaluating candidates, they also come with potential risks. Overemphasizing brain teaser performance may lead to the exclusion of highly qualified candidates who may not perform well under pressure. It may also place undue stress on candidates, leading to anxiety and nervousness that can negatively impact their performance.

Furthermore, brain teasers may only assess an individual’s problem-solving ability, whereas other important job-specific skills may not be evaluated. Thus, it is essential to use brain teasers as part of a more comprehensive evaluation process.

While brain teasers can provide valuable insights into a candidate’s critical thinking ability, it should not be the sole criterion for evaluating job performance. It is important to use a combination of various assessment tools to ensure a fair and accurate evaluation of a candidate’s suitability for the role.

The Future of Brain Teaser Questions in the Hiring Process

A. Trends in the Use of Brain Teaser Questions

As the use of brain teaser questions becomes more widespread, it’s important for hiring managers to ensure that the questions are relevant to the job and provide a true measure of a candidate’s abilities.

B. The Benefits and Risks of Using Brain Teaser Questions

The use of brain teaser questions in the hiring process has both benefits and risks. On the one hand, they can help managers identify candidates who are able to think critically and creatively, which may be particularly important for roles that require problem-solving skills.

Brain teasers can also be a good way to differentiate between candidates who may have similar qualifications and experience. Additionally, they can give candidates a chance to showcase their skills in a way that traditional interview questions may not.

However, there are also risks associated with using brain teaser questions in the hiring process. For one, they may not be a fair indicator of a candidate’s overall abilities or potential for success in a role. Additionally, some candidates may find them intimidating, which could create a negative impression of the company.

To mitigate these risks, it’s important for hiring managers to use brain teaser questions in conjunction with other types of interview questions and assessments. Additionally, they should be transparent about the use of brain teasers and provide candidates with adequate preparation time before the interview.

C. Future Innovations in Brain Teaser Interviews
