First, phone call with the hiring manager (30 mins). Second round consists of three technical interviews on hackerrank (45 mins each). Each interviewer will waste time asking questions about the current project and suddenly expect you to write working code for the problem. Then comes the Caliper test which will take 2 hours of your time.
Third round is on a per case basis, not everyone will have it. I had three interviews for the third round. The first two are again technical and general chat. The last one is salary negotiation which doesn't make any sense since they won't tell you if you are getting an offer or not. Looks like this is about saving money and compare candidates based on their salary expection. Overall, it was a waste of time since you may not get an offer even if you do good on technical rounds.
The assessment included simple coding questions about Maps, sets, and data Structures.
