Interview Puzzles: 5 Common Difficulties and Their Solutions

It may come as a surprise to learn that interviewers frequently test candidates with tricky logic problems. It may come as a surprise to learn that puzzles and riddles are frequently used by interviewers as a means of testing candidates’ critical thinking and problem-solving skills. These kind of inquiries are popular in the IT industry, where they are used to screen candidates for roles like software engineer, developer, programmer, etc. Interviews for the police, the military, and various administrative professions often include such tests of critical thinking and decision making.

Can you tell me about some interview puzzles?

Puzzles are a type of logical thinking issue, similar to a brain teaser, that can be used as a test of your deductive reasoning skills, wit, inventiveness, and ability to perform under pressure during an interview. Let’s take a look at how you can best prepare for puzzle interview questions, as well as some typical questions, their answers, and interviewing strategies.

How to Solve Confusing Interview Questions

While it’s understandable if you’re stumped by some of the interview questions, you should be able to answer them with relative ease. Some strategies for solving interview puzzles are as follows:

1: Take your time.

The most common candidate error is a rush to get an answer out. Even if you have a fast reaction time, you should avoid this. Try to avoid jumping to conclusions and instead give some thought to the topic and the issue at hand. If you believe you’ll need more time, politely ask the interviewer for a moment.

#2: Seek further elaboration

Riddles and puzzles are purposefully difficult to solve so as to throw off the reader. Be sure you have a firm grasp on the underlying question structure before diving in to a solution. If you need clarification, you should ask the interviewer for it. Do not worry that you may make a bad impression; the interviewer will value your sincerity.

Open your mind, number 3.

It’s important to keep in mind that, no matter how good you are at solving puzzles, there will always be one that’s trickier than the rest and calls for a different strategy. Do not become too comfortable with your current level of skill. Explore all of the options and conduct experiments if necessary. Using these examples, the interviewer can evaluate your ability to think analytically.

Fourth, give an explanation for your answer.

Responding succinctly and directly to interview questions is highly valued by most employers. When answering a puzzle question, though, it’s preferable to provide an explanation of your thought process in addition to the solution itself. The interviewer can get a sense of your analytical thinking and deductive reasoning abilities, as well as how you approach solving problems systematically, by asking you these kinds of questions.

Five, always respond

The effort put into applying logic to puzzle questions is more valuable than a correct response. You should always give an answer to a puzzle question during an interview, no matter how erroneous you may think it is. It’s possible that the interviewer will pose questions to which there are no correct responses.

Five Typical Puzzles for an Interview

In a job interview, you can be asked a variety of brainteasers that would be impossible to predict. However, there are recurring ideas and methods for fixing issues that appear in many of them. Here are the answers to five of the most popular questions posed in interviews, so you may prepare for the challenge ahead of time.

First Example of a Resonant Reponse

I’ll ask each security guard the same thing: “Which door would you point to if I asked the other guard to help me find it?”

The guards will give you a confusing response in which both of them will point to the wrong entrance. So, I’ll eliminate the other one and leave that one in.

Second Suggested Reply

My plan is to have the security personnel unlock the entrances. Seeing as how I did not initiate something, I should not be held accountable for what happens next. As a result, I will be able to see what is behind each door and make an informed decision.

Exemplification of a Reply

Hold 5 different races, each with 5 horses. The victors from the first five races should then compete in a sixth race against one another. A horse with the fastest time at the finish line wins.

When just four horses remain from the sixth race, hold another one. The top two finishers in this race are the second- and third-fastest equines overall.

Answer example

There is an equal likelihood that all four ants will never meet and an equal chance that at least two will.

Since the ants may only go in one of two directions, clockwise or counterclockwise, the initial 50% possibility of them meeting is reduced to 25% (since half of 50 equals 25).
