Oracle Software Developer IV interview questions

The interview process was decent. They had a telephonic round and asked to come for a face to face discussion. The interview started on time and the interviewers were courteous. Had 3 round of face to face discussions. The process was smooth but the only disappointing thing was the HR did not contact back until a month (or probably 5 weeks)

HR called and scheduled interview even though i told them that i was a misfit for the requirement... there were 3 rounds of interview...the technical interviewer asked me my salary which i didnt like. he gave some performance problem to solve..followed by another round where he asked to find complexity of some programs and followed by another round where they asked couple of programming questions...at the end they said they will get back to me (which obviously means they didnt like me) and i also didnt like them due to the interviewer attitude..they were very disinterested in the whole process..
