The first step was an online coding assessment. It lasted 48 hours and, in my opinion, featured a very good selection of problems. The second step was a review of solutions, followed by an onsite interview. This onsite interview was 4-5 hours long

Behavior screen: about 20 minutes. Technical screen: 2 rounds. * 45-minute technical interview * 1-hour system design * 1-hour live coding test Final screen: 3 rounds. * Conversation with the Tech Trainer * Behavioral Interview * Tech Fundamental

A lot of interviews. Started off with a call, then some online tests. Then a technical interview. Then a live coding interview along with an architecture interview. Last step would have been a final day interview, but I did not get that far.
