it takes around 3 stages, and overall questions are not so hard, need to be prepared before attending the interview.
Also remember some basic knowledge about hr, like main responsibilities, etc.
Spoke with hiring manager and they were hesistant to share much, afraid of leaking anything about their model training. Makes it hard to understand the role. Also got asked about being able to speak mandarin. As with all my other interviews with the company, HR will ghost you after and does not bother to even send a rejection.
HR reach out to me invite me to take a Data Scientist interview, and scheduel an interview for me. I only took one interview asking about project-related questions,and some questions about statistics, experimentation, and modeling,and one open-ended question.
