I applied online first, but received no response in a month. Then, I asked a friend to refer me, and I got a response in three days.

There were three technical interviews. I felt lucky that each interviewer started with an easy question, which I completed within 30 minutes. After these warm-up questions, each interviewer posed another, as difficult as medium LeetCode questions. However, they did not expect detailed implementation; instead, they wanted me to explain my approach to the problem. I was totally lost on one problem and worked out pseudo-code solutions for the rest.

I just finished the interview and have no idea how it went, but I felt it was normal and not scary at all. I hope to hear good news from them later.

I signed an NDA, so I cannot go into detail about each question. However, one question was about a 2D matrix, and two were about string operations.
