I had to leave because I was sick of always doing my colleagues' work for them. They hire young people out of college who don't really understand anything and don't try to learn things themselves. A lot of people are lazy and I got tired of constantly having to pick up the extra work. I went to management about it and was basically told to deal with it and that I should be there to help my coworkers. Just don't bother.
It was also hard to move to a different team because they're always hiring people externally instead of internally.
