I had a great overall experience interviewing, with four rounds conducted by different team leads. Each interview followed a similar structure: a brief introduction to the role, followed by a discussion of my background (resume and projects), and then a technical portion focused on problem solving (LeetCode style questions). The first three interviews went very well, and I felt comfortable with both the format and the level of difficulty. In the final interview, I made a rookie mistake by mentioning that I had seen a similar problem before. In hindsight, this isn’t ideal - it can put the interviewer in a difficult position when assessing your skills and may unintentionally raise expectations. It’s like telling an examiner during a test that you’ve already seen a similar question before - it doesn’t change the situation, and you’re still expected to solve it and demonstrate your understanding. In terms of preparation, I’d recommend going through "Cracking the Coding Interview," solving a large number of LeetCode problems, and making sure to rest well before the interview. Overall, it was a positive and well structured process.
