The interview process includes four rounds of technical interviews and two rounds of HR interviews.

The first three technical rounds are crucial. If you pass those, the other rounds are just pass-throughs.

The technical rounds begin with very easy questions to make you feel at home, but they progressively become tougher as the interviewer drills deeper into subjects you like. The key is to let the interviewer know what you are good at beforehand.

Each of the first three technical rounds typically takes 45 minutes to 1 hour.
