Went straight into coding problem once the video call started, without any introduction or other converstion. Typical technical interview with coding problems of leetcode hard level. Also asked some machine learning conceptual questions.

Question 1
How do you calculate AUC given a list of positive and negative instances sorted by the predicted score?
It was ok. There was a coding challenge followed by 2 interviews. Coding challenge was doable. 2 interviews lasted 1.5 hours each. One peculiar thing that happened was during the interview process they switched the exact team i was interviewing for 2 times.

Question 1
The HR call was very short and I did not get asked behavioural questions. The HRs are very nice and reply to emails very quickly.
Then the technical interviews. It seems that they have a pool of questions that are shared with all engineers. So the first interviewer asked me backend questions even though I applied for MLE. The interviewer was nice about it when I told them that I have not learned certain topics in school.
I was asked about the Machine Learning projects on my resume. They wanted to see how well you know the specific concepts and ML algorithms you used in these projects.
For the coding challenge, I got a pretty easy question in the first round, about designing a cache. The question asked in the second round was quite difficult and required dynamic programming.
Also, even though the interview started in Mandarin, the interviewer switched to English when I told them that I did not know technical terms in Chinese. We had no problem in terms of communication.
