Oracle Senior Build and Integration Engineer interview questions

I was interviewed for Oracle Bengaluru location. Total 3 rounds - 1 HR screening, 2 technical. Both technical rounds went good and in 2nd technical only 6 questions were asked out of which I answered 5 correctly. However, I didn’t get any update after 2nd technical round and after follow up mail , I received rejection mail. Again same day after few hours, I received call from HR that my profile is 50:50 shortlisted so I might get call for further rounds. But no update after a week too. It seems my profile was kept for just backup ( not sure if it was due to CTC ) As candidate invest time and efforts for interview . so his/her time time should be valued if interview goes well.
