Easy interview, friendly team, collegiate atmosphere it seems. Be warned though, after an hour or two, not in the beginning or early stages, you will be told how much you get paid. If you get offered below minimum wage as I was, simply walk away and say good luck! It is illegal to offer below $11/hour in NYC in 2017! A waste of time!
Also, professional courtesy isn't much to ask for for a candidate who spent 2.5 hours in your office i.e. please respond to an email like a professional.
