Oracle Software Developer interview questions

I started the hiring process through my university. First I had 2 interviews the same day just about general programming concepts en logic. One month later I got other 2 more interviews, these were more technical. At the end of these interviews they told me I was advanced to the "final list". 10 days later I got an email telling me that a specific team in MDC wanted to interview me inmediately (the same day I received the mail or the next). I did my Interview by Skype the next day and I did very well I think, At the end of the call the team told me "We want to make you an offer". 15 days later I have not received new information since that day.
