You are going to find the same old corporate BS that you find in every corporate job. There is a LOT of drama and back stabbing. The people I were "Honored" to work with were well seasoned.
Working in the IT department I saw many older (over 40) people dismissed only to be replaced by younger, "in-click" people. Even some in mid management positions who didn't fit in the group were replaced. This seems to be systematic and most likely illegal but honestly, if you take a look at the IT department (Helpdesk, workstation, tier-2 and various other teams) you will honestly notice a generation gap. Department managers don't seem to notice, nor do they care. It's corporate after all but it is also obvious and very sickening to watch.
