There were three interviews in total. One interview was a high-level discussion phase on how I would approach a problem. The other two were one hour each, split between a coding question for 30 minutes and ML research-related questions. There were follow-ups on how you would improve the code. The interviewers were friendly.

2 rounds of interview for minimum, max. 3. The interviewers mainly focus on 1. your language ability, 2. your past experiences (any projects/internships/relevant experiences). The interviewers cares a lot about your past experiences, like how you worked on a project, the technologies you have used in the past, and how you approach a problem encountered.
