Google Project Manager interview questions

lengthy all day affair with back to back interviews. most everyone was great but asked me a programming question for a language I had not done in 20 years, while the interviewer said this was a mean question he was still going to ask. that being said the methodology of hiring based on difference of opinion meaning if 5 people love you and one likes you then they don't hire more particularly they all need to like you the same is strange to me but otherwise was a pleasant experience
