[UnnamedGamedev]

This seems incredibly unprofessional to me. I'm an indie gamedev; my friends are mostly 4chan posters, perverts, and unemployable layabouts. WE know not to tell deliberately offensive jokes in a professional context, how can Crytek's staff not?

I don't have much experience looking for work with normal employers, so I can't give you anything firsthand about how pervasive this sort of thing is, but what you describe seems abnormally bad.

One thing to note: AAA development (at least in the US) is known for terrible working conditions. If you want to go into game development, make sure you get a good idea what the studio you're applying to will actually expect before you accept a job.
