I had one question about graphs and binary trees. It was about 45 minutes. The interviewer was good. I didn't submit a perfect solution. I could do better, but unfortunately, I didn't pass the interview.

On-site interview of about an hour with one interviewer. A few minutes of "tell me about yourself," followed by two easy questions. They expect you to answer fast and write clean code.

It was pretty straightforward. We had a few laughs on the way to the interview room, and then we started with questions. The interviewer was so kind. He didn't make me feel uncomfortable or like he was in a hurry.
