I wish I'd read up about the stability of the company I'm joining and if they're financially sound or not. Companies that aren't doing well financially usually have problems with management (for example, projects don't get enough funding).

Another thing I missed is if the people on your team sound bored or don't seem interested or excited about their work. One way I found telling was if they didn't go into details about their projects and try to be ambiguous.
