When going to interviews, I often want to take a peek at how the company works on the inside, but they may not show you everything or want to "keep up appearances" to make them more inviting. Obviously the latter is expected when management wants to really sell the job to you, especially if the company is a well-talked about brand.
But then there have been those times where I take a job and some nasty skeletons come out of the closet.
An actual experience follows: An owner of company A interviewed me and mis-represented his company by showing a large work environment, when in fact all that space belonged to a different company B. He told me A and B are in a partnership so I assumed the space was shared. It was not until a month later I found out that A's owner works for B and subleased a small space from B to run company A on the side. So A's own employees don't represent B, work in a cramped area and receive no company benefits from either A or B, as A is too small of a company to afford fancy things like that.
There wasn't much info about his company online, so it was hard to do research on. How to I look for warning signs like this in the future, before I take the plunge and find out when it's too late?
