What should I do if I encounter a question I don't know during an SDE interview?

First of all, it is very normal to encounter questions you don't know in an interview. So what should we do?

1. Adjust your mindset

It's easy to panic when you encounter a problem you don't know how to solve, but the more panicked you are, the less you know where to begin. At this time, we need to adjust our mindset, take a deep breath, stay calm, and calm ourselves down to think about the problem.

2. Ask the interviewer for advice.

If you truly have no idea how to solve it, you can ask the interviewer for help. However, when asking, be sure to explain your understanding and ask for hints or directions. Some students have directly told the interviewer they couldn't do it, and the interviewer simply gave them a different question, but this is not recommended.

3. Try different methods

After the interviewer gives you hints, you can try using their methods to solve the problem. If that doesn't work, you can try other methods. Actually, the interviewer doesn't care what method you used; they only care whether you found a solution and a thought process for solving the problem.

4. Communicate with the interviewer

Finding the correct answer is only one aspect of problem-solving. Maintaining good communication with the interviewer is crucial. Interviews differ from exams; they also test your interpersonal skills. You can explain your thought process and the problems you encountered while trying different approaches. This allows the interviewer to better understand your thought process and provide timely feedback.

5. Don't give up

Even if you really don't know how to solve the problem, try your best until the interviewer tells you to stop.

6. Learn to summarize and reflect

After the interview, don't forget to summarize your performance and think about where you could improve. This will help you better handle similar questions in future interviews.
