Very cordial. First round with hr, then hiring manager, then global manager, then again HR. Could take a month or two for the whole process to complete and receive your offer letter.

started with a call from the HR asking for a phone interview with the hiring manager. After the phone interview, about two weeks late, went for an on site interview which lasted for a whole day from 9 to 5 including a presentation following by 9 half-hour 1-on-1 interview.
