The process includes the 5 rounds. The rounds followed by HR, then with ML engineer, then will have 4 more rounds with respective team members. The questions are on basic ML, Python and Sql.

The recruiter called me out of the blue without an email to ask for my availability. I should have taken this as a red flag. He set up a meeting with hiring manager which was okay (standard questions) but the rest of the interview process was a disaster. Next step after the hiring manager was supposed to be a coding screen (Python/SQL) and after this - virtual onsite. Instead, recruiter scheduled 4 one-hour meetings for Monday with less than 24 hour notice (literally scheduled everything on Sunday and I didn't get a link to join meetings until 1 hour before the first interview). No breaks between interviews. Most questions were repetitive and boiled down to "can you create linear regression models very quickly with constantly changing deadlines and requirements from the stakeholders". I would avoid this company if you can.
