Entretien
Recruiter reach out. Then recruiter conversation. They want to match you with a team before interviewing you. So I waited almost 2 weeks to get matched with a team. After that was a phone screen - leetcode medium. For onsite, there are 2 ML design rounds, 2 coding rounds, a hiring manager round. Took almost a month to finish that off.
