The interview was unprofessional by young kids who did not prepare at all for the interview. They seem unsure of the job duties, the hours, what was involved, etc. It seemed as though I was being interviewed by undergraduate interns. I might have made them uncomfortable by asking too many difficult questions which made the interview awkward. I like working for smart people and age is unimportant but the guys here seemed to lack experience in life or passion for anything. They might have just gotten to work and might have totally forgotten about the appointment. This was in downtown SF office. A total waste of time.
