I had an outstanding offer from another company, so they were quick to fly me out to SF to meet with me after the initial phone screen with the hiring manager. I met with 6 engineers and product folk. They were the typical, so "tell me about yourself" questions (2 of the interviewers had obviously not read my resume and asked me that while they scanned my resume). Two of the interviewers had marked up my resume with a red pen and asked me design questions, questions about the competition, about the real estate market, etc. Those were engaging conversations. I'd spoken to the hiring manager on the phone twice already so most of our conversation was not about work. It was just to see if there would be a fit. I was sure I'd get an offer (I did not).
