Oracle Senior Software Developer interview questions

I got a call from Oracle regarding opening for a developer position. There were 5 rounds of interview: 1. Telephonic 2. Written round 3&4. Technical face to face one was about programming and other was about domain. 5 Director round. I had cleared all the rounds and HR had asked for supporting documents to process my profile. But after that there is no communication from HR regarding the processing. I have no clue what happened and there is no response from the HR for the mails. They do not value others time and there is no formality of responding.

I was first interviewed by a recuriter, who of couse did not ask any technical questions. Then I was interviewed by several members of the group that I would be joining. In my case the interview questions were very light on details, but that was undoubtly because I was extremely experienced.
