What Are Interview Puzzles?
Interview puzzles are critical-thinking and logical reasoning problems that make candidates use their problem-solving and analytical skills to find a solution. Interviewers prefer to ask these puzzles because it helps them understand your thought process, and your ability to solve complex problems using strategies, and high-order thinking. Usually, candidates applying for software development, data science, or engineering roles may encounter such puzzles. Much like brain teasers and logical reasoning questions, puzzles for interviews may not directly relate to your job role.

By practicing commonly asked puzzles during an interview, you can increase your chances of answering the question correctly. Additionally, how you approach a problem may impress the interviewer and give them evidence of your ability to solve real-world problems.

How To Answer Puzzles For Interviews
Here are a few steps to follow to answer puzzles for interviews:
1. Take some time to think about the problem
Before answering a puzzle in haste, take a moment to think about the puzzle and its category. For instance, an interviewer may ask you a riddle, brain teaser, or a number trick puzzle. Once you understand the puzzle, you can use different problem-solving strategies to find the correct answer.

2. Seek clarification and ask questions
Puzzles and riddles can be confusing and you may misinterpret a part of your puzzle. Rather than finding the solution based on your misinterpretation, it is always good to seek clarification from the interviewer. Asking intelligent and meaningful clarifications tells an interviewer that you are not hesitant to seek information or resources to complete a task. It also shows that you are thorough and curious.

3. Use strategies you know
Most of the puzzles an interviewer asks may involve the use of basic mathematical concepts. So, instead of inventing a new formula, use strategies and concepts you already know to find a solution to your interview puzzle. This can help you ensure you find the correct solution.

4. Explain your answer
As you work through the puzzle, you can show the process and reasoning to the interviewer. This can help an interviewer understand your thought process, your ability to plan and execute problem-solving under pressure. Even if you fail to get the answer, the interviewer knows how you approach a problem and use your analytical mind to solve it.

5. Provide a solution
Usually, an interviewer does not ask puzzles to get the right answer. They ask puzzles to gauge your logic, reasoning and critical thinking abilities. So, even if you know your answer is wrong, provide a solution to every interview puzzle during your face-to-face interaction.
