Some poor management - My manager was never around, always working from home (which isn't an issue except no one in my group saw any work get done by the manager).
Cold culture - People weren't very outgoing/friendly in general, my guess for the average age is ~40, people didn't seem excited about their job in general. It just felt more professional and rigid than I prefer (but I prefer a bit more of a relaxed culture which is hard to maintain in a large company). Also, I remember my manager telling me several times how things "used to be" before TALX was bought by Equifax. They used to have BBQs or whatever and overall it seemed like a more fun place to work. Fun would not be a word I would use to describe working there so it concerned me what direction the company was going. Another example is the Holiday/Christmas Party which was a lunch offsite, during a work day, that lasted just barely over an hour...wow.
While I was there a co-worker in my group had to work so much overtime for a proposal. If I had to guess she probably worked at least 80-90 hours that week. After I left, my friend who works there had to work several 12-16 hour days to keep up with the workload (one person left the team and the manager didn't help out) I don't believe this is the norm, but it made me think that work/life balance might be a little off there.
Like most office work, much of the time it is boring
I agree with one reviewer who talked about silo'd departments, us vs them mentality, lack of standard processes throughout creating extra work for people trying to work together/use the same information. For example, the marketing group had wonderful graphics that they used for who knows what but my team sent out proposals to possible clients and we were using old graphics and mad up graphics because we weren't given access to the new graphics for some odd reason. Why wouldn't you want everyone to have access to sending out graphics that brag about the company?
