Oracle Senior Software Developer interview questions

I was initially contacted by HR. During the initial discussion they gathered basic information about my profile and also briefed me about the position and what actually they are looking for. After a few days first round of technical interview conducted. Basic to intermediate level questions asked about Oracle db architecture. All facets of Oracle products were touched. This was further followed by second level technical interview. This was quite intense and lengthy. Both rounds were telephonic and duration was more than an hour for each. Second round was to check depth of knowledge with few issue specific questions. Before third round few documents collected by HR. Third and fourth round taken through video conference. Third round was with hiring manager. In this round technical and behavioral qualities were assessed. Salary negotiation also took place in this round. Next was fourth round with the Sr.Director. Mostly behavioral questions. Verbal offer made after few hours. After 3 weeks soft copy of the offer letter released.
