There are overall 3 round
Round 1: Problem Solving, DSA, Algorithm, Database
Round 2: System Design Round
Round 3: Hiring Manager/ Director of Engineering Round
There is positive feedback from HR after all of the rounds. Then they haven't replied for a couple of weeks after that. It seems like there isn't enough budget for this position.
I have already found lots of similar interview experience. These guys aren't serious enough for hiring and just wasting their and our time.
