Applied for a Senior DevOps Engineer position. Talked to recruiter then had a screening call with the hiring manager. Got a take-home assignment to complete which was relatively easy, finished it in a few hours and then had to do a presentation to their team on it. Followed up with 2 technical interviews and behavioral interview. They ended up giving me a very generous offer, I interviewed for a Senior role but got an offer for Principal based on my skills and feedback. The equity was much more than I asked for while they matched the salary ask. I accepted their verbal offer but found out the week after that the offer had been rejected by Oracle management which was very disappointing given the time and effort spent on the interview process. No reason was given as to why it wasn't approved but I'm guessing it's related to the hiring freeze they have (and the fact they wanted to give me a Principal role). Would really love to know why or if I could have done something differently. Having the offer rugpulled on me like that seems unprofessional from such a large company but then again, what can I do about it?

I had an awful interview experience with Oracle. First round was telephonic one and post multiple follow-ups I got an update after 10 days. Second round was rescheduled for 3 times but it didn't happen. HR never approached the panel before the interview and doesn't know about the status until I update her. This proves the irresponsible nature and unprofessional ethics followed by them. Please don't approach the resources if there is no requirement (just for showcase) and kindly treat everyone's time is important.
