2-3 rounds of interview, first round
is technical , second round is with manager , final round is with hr and salary discussion .
You have to technical sound for clarifying the interview rounds
I applied through a recruiter. The process took 3 weeks. I interviewed at Birlasoft in Dec 2020
Interview
Interviewer asked mostly technical questions ranging from statistics to machine learning to cloud computing which I answered quite comfortably and the interviewer gave nice feedback but later came to know through the HR that interview didn't give positive feedback to them
