I was previously rejected for one of the team positions, and HR had my CV. HR then called to check my interest in another position, and an interview was scheduled for the following week.

There were a total of four technical rounds. Two were in-depth discussions about the job profile, and the other two focused on general domain knowledge. There was also one director round, which was more of a formal discussion about the team they were hiring for.

All interviews happened on the same day. The HR round occurred over the phone two days later.

I received an offer two weeks after the HR round.
