I was summoned to a nondescript industrial building, found my way upstairs and wound up in a grubby room posing as a lobby. I was seated on a low futon and had several discussions with my knees nearly level with my ears. The conversations were overly casual but with some oddly specific IT security questions. I seriously contemplated walking out of what was clearly an amateurish, shoestring operation.
Nope... I have worked there 20 years so far.
My first job was to evict the former sysadmin, and within the first 90 days I was relocating the whole company, building out the new IT infrastructure.
So in the spirit of the recent post about Charlie Munger killing a lot of pilots I would suggest not judging the company solely by its lobby. Make a list of real deal-breakers and consider overlooking the rest.
