Uber Recruiter interview questions

I went through a couple of rounds of phone interviews, then 3 rounds of onsite interviews, 2 in San Francisco, one in Palo Alto. I have no major issue with the planning for the interview, but it seems like an inordinate amount of time, to eventually be told I do not have the experience they were looking for, after feedback from prior sessions was so positive. I mean "not enough software engineering experience", after an 11 year career? Give me a break!
