I only got to do the first step of the interview process, which is an online test that lasts about 3 hours and has about 4 stages to it. It consists of mental math and a bunch of games, then at the end there are some brainteasers/prob. questions and behavioural questions. If you pass this first online step, you would be scheduled for a behavioural interview and then a final deadly difficult interview for about 3 hours.
