Oracle Principal Product Manager interview questions

Very lengthy process. The entire process took about 6 months. There were 4 phone interviews- each around 30 mins--these were all technical. The phone interviews were spread over 2 weeks and started about a month after I first submitted my resume via LinkedIn to the recruiter. A month after the last phone interview, I was called for an onsite interview. I met around 6-7 people there---most of the sessions were technical and were focused around my knowledge in the space and experience in the field --these were with various other product managers and engg managers. I was asked to prepare a presentation beforehand on a given and the final session I was asked to present for 30 mins to that audience. After 6 week from the day of the onsite interview I was called and told that they would be making a verbal offer. A week after that I was made a verbal offer. I negotiated the verbal offer--that took about 3 weeks. A month after that I got a call that I was hired.
