I applied through my school's coop job system and they tattled on me! The school doesn't allow communication between prospective employers and students...but Microsoft does all its communication outside the system and the school does nothing. I got another offer outside the system, and needed to give an answer. I reached out to the recruiter asking when offers would come out (this is common practice), who said she couldn't tell me, and then next thing I knew I got an email from the school telling me off for going "outside the system". The employees and recruiters are weird and culty about working there, too. They try very, very hard to impress 18-22 year olds. This was a couple years ago (writing this to get more Glassdoor access lol) but their nastiness in ratting me out while breaking the same rules hasn't escaped me.
