Worst experience I've ever had with a company. The people were nice, I was told afterward that I would receive an offer the next day. After waiting three weeks of unanswered emails and not calling when he had said, ended up not getting an offer because I wasn't interested in traveling 50%. A travel requirement was never mentioned until after the formal interview, but apparently the HR guy just wasn't aware of it.

HR screen phone call, phone call with cost analyst, and then 2 in-person panel interviews. Everyone I interviewed with was nice, and I thought it went well, except for the CEO, who ranted about working hard and how if I didn't know how to work hard, it wouldn't be a good fit.
