Oracle Software Developer interview questions

The process took over two weeks due to a bunch of holidays and never heard back from. The hire manager and a few others were nice people but the people conducting the technical question parts was mix. One guy just had no patience and the other was nicer but talked too much. The questions asked were simple enough.

The interview process consisted of 4 technical rounds, 1 hiring manager round and 1 BT round. First Round- 2 coding questions to run with test cases + some basic managerial questions. Second Round- Questions were around resume specific skills + coding questions + managerial questions. Third Round- Questions were pretty basic related to UX and most of them were managerial questions. Fourth Round- Coding questions (difficulty medium) HM Round- Discussion around the work and Q/A BT Round- This round is taken by someone who is not a member of the team that the candidate is being interviewed for, to ensure the quality of candidate across the company. The BT round was pretty vague and not at all on point. The interviewer first asked me what all domains am I comfortable with, then started asking questions unrelated to those domains. Whatever questions I was asking him, he was cutting my questions and started asking other questions. All technical rounds + HM round went pretty nice (according to me), but the BT round was pretty vague, the interviewer was looking at the time again and again and the questions were very random too. The panel was from US, so the timing of the interviews were also pretty odd. Did not receive an offer. Requested the HR for feedback, but still didn't receive any.
