I'll add to the list. Be aware of org/process changes. For example, I was working for a company who had been acquired a couple of years earlier. They were transitioning from analog to digital, but were slower than most competitors and weren't doing too well. One day, there was an announcement that some of the merged sales channels were being un-merged. The writing was on the wall, the business unit was being separated in order to sell it off.

It was an easy few months to find another job, and sure enough a bit later the company was sold to a VC firm and then again to another corp. Things could have been fine for me, but I honestly didn't want to go through the two ownership changes. My lesson? The information usually isn't too hidden, you just have to understand the implications of the emails that you usually pass over.
