So if your new employee doesn't give you warm fuzzies- let them go fast? There are lots of great talent that is neither an anti-social asshole, nor a social butterfly; there has to be a some minimal time to "get to know" the new guy. It sounds like this guys is hiring for a frat-house.

Also, Warning signs- Randy mentions "9-5" and "as they say goodbye at what you may not deem not a legitimate end of the day."

I don't think I would want to work for Randy- Maybe this is just my impression and not the case here, but if you think being a startup is an excuse for regularly expecting employees to work more than 8 working hours a day then you are deluded, taking advantage of your employees and hurting them. I would not let my employees work more than 50 hrs/week even if they begged.

Side thought: Everyone in the valley mentions 9-5 as "standard working hours", but a standard work day is 8 hours. So assuming a 1 hr lunch that is 7-4/8-5/9-6... Where I grew up in the upper midwest, there everyone used the term 8-5...
