2 rounds of interviews
1st round: Presentations by recruiting teams and get to know each other sessions. Two 15 mins technical interviews. These are mostly to screen off obvious non-hires. Questions were pretty basic and only to determine who-you-are, but not how-good-you-are.
2nd round: 1 hr technical interview and 1 hr senior management interview. Verbal and numerical reasoning tests. Technical interview was by a panel of 3 interviewers, who varied the level of difficulty based on the answers. Senior management interview was about career goals and objectives.
