HR contacted via LinkedIn and set up the schedule. They'll provide you with details of what topics to prepare. A total of 5 Rounds will be there. I interviewed for the role of the front end. My only disappointment was I wasn't sure of what to expect in R1. My suggestion to the HR team is to be more specific about what round it will be like DS/Algo or M/C coding. Otherwise a great interview experience. The Interviewer was also very polite. Did give feedback in the end and got a response about my application status the same evening
