Do not waste your time interviewing with Oracle. They do not value their candidate's time and do a very poor job of communicating throughout the process. I had to prepare a 15 minute presentation to present in front of a panel, come in for second "cultural fit" interview they neglected to mention at the start, and they dragged the process out over almost a month. Expecting an offer based on the feedback I was given, I emailed to ask them for an update after two weeks had passed. I got an vague email reply three days later saying "we're going in a different direction". No phone call, no communication from HR, and no further clarification to their decision after I devoted hours of my time to come in to interview from out town and held off from applying to other jobs because I was under the impression things went well. There's so many amazing companies in the high tech industry that treat their staff and prospective recruits well, but Oracle is not one of them. I was skeptical reading the reviews on Glassdoor at first but they're definitely true.
