Got asked about the models I used. Past experience. LGBoost and why it's fast and efficient etc. Overall interview was ok but don't know what they want. The interviewer didn't like the background I had.

hackerrank -> 2-4 technical rounds -> final round with PM -> BD. The process is fairly quick and concludes within 4-8 weeks. Interviewers were professional, quick fire. Hackerrank is LC medium.
