CA Technologies Senior Web Developer interview questions

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.
