1 -> 2 coding questions as filtering round 2 -> application to parse corn expression 3 -> discuss approach followed + add more use cases 4 -> Behavioral round 5 -> System design : sell 6M burger in 10mins : Interviewer joined the call late, put the question and was not interactive at all during the solution approach. 3 times dropped the call saying having network related problem. From my end I explained well in detail about the approach I'm taking and why. She didn't know actually how to take a SD round basically.
