Oracle Senior Software Developer interview questions

Most useless company i have ever attended. Even though interview was well planned, there were three technical rounds. and i was able to clear all of them but no call from HR after that. I don't know weather they have requirement or not but they wasted my one whole week. when ever i called manager who had taken my interview he said profile is with HR they will come back to you if they want. i suggest candidate who are in real need of job then don't waste your time by attending this company interview.

send an assignment as an OA, follow by phone screen by HM, then a onsite 4 engineers and one HM interview. All of them are coding questions. Only one has a design question but it is very simple.
