Got direct call, interview process were fast enough. Had initial technical round covering basics, went on to another technical round testing little more deeper, and later went on to a algorithm/ data structures round and then a managerial round were 2 managers explained about the product. And after everything i was told that i was through with all rounds and the HR will contact me, then later after a week I was contacted and said they need approval from the VC/VP as he is travelling and later even after that got another call saying they still dint get approval and then finally no calls.
