The interview was conducted in a pair programming style.

First, the interviewer introduced himself.

Then, he asked a class design problem.

After I completed the first part, he continued with follow-up questions.

Each question required the implementation of a specific function or interface.

The problem-solving portion took about 45 minutes.

After that, I had 10 minutes to chat with the interviewer.

The interviewer was very nice and helpful!

I cannot disclose detailed questions. The questions are more like model questions, not algorithmic questions like those found on LeetCode.
