Oracle Sr Software Engineer interview questions

One of the worst interview experience I have had in this round. As a technical person, we should be open-minded and seek multiple solutions as a possible technical solutions to solve a technical problem. When this interviewer asked me a question about dependency injection, which is a topic am pretty familiar with. I offered a few possible solutions which is pretty standard and elegant ways to handle the case, the person was not happy, he just fixed in his mind one specific solution. It showed his narrow-mindedness as well as a broad technology background, btw interview with Oracle is always unpleasant, a few years back I had a full loop with the company, and there were two separate interviewers who didn't know the correct algorithm for the exact questions they asked. Coincidently when I implemented the most optimal solutions both of them saying my answer had bug in it, when I walked through the execution with the example they gave, they couldn't point out what was wrong and had to admit my solution worked. In the end I was getting a rejection letter, I wouldn't join a team with members of such technical capability any way. BTW in that round I got multiple offers from companies much stronger than Oracle.
