Oracle Senior Software Engineer interview questions

I scheduled a phone interview shortly after applying online. The interview consisted of questions regarding previous experience, interests, and my availability for an on-site interview at Oracle HQ. At the on-site interview, I met with the hiring manager and four principal engineers. In each interview, I was asked about previous experience and/or provided challenges. The challenges were standard white board coding problems. Overall, I found the communication skills of the interviewers to be below par. The manager being the worst and the carried over to the post-interview process. After the on-site interview, I received no further communication from the hiring manager. After two weeks, I reached out to ask about expense reimbursement and whether I was still being considered for the position. The manager seemed put off by the question and responded with a curt email that directed me to a FAQ document. That document, mind you, states that you should reach out to the hiring manager for questions regarding expense reimbursement. Once I explained that to the manager, he had me email him the receipts. Note, however, he never address the other question regarding consideration for the position. That's fine, I thought. I'll ask again later. Four weeks pass with no communication from the hiring manager and no expense reimbursement. I email the manager asking for an update on the reimbursement and the position. Finally, I learn that I am no longer being considered for the position. Now, one could assume that from the lack of contact. However, I feel it was disrespectful to say nothing after having me come out to Oracle HQ and spend a day with the team. Regarding reimbursement, he didn't have any answers. I asked for a contact within Oracle HR for his team and he all but refused to provide one. After getting the run around via several correspondences, I called Oracle's main number and was transferred to the HR hotline. After a few minutes of waiting, the system put me into voice mail. I left my contact information and a brief explanation of the problem with reimbursement and the manager. I am now waiting for a response.
