I wouldn't believe the "many engineers at senior level" part without further evidence. When I was there for eight years, there was a consistent pattern of people being stuck below their proper level because any given manager could only promote so many per year and people had to "wait their turn" no matter how much they deserved the change. That was all before the IBM acquisition, but not by that much and even in context I'd be surprised if things had changed that drastically.
