I worked in the ISS department and the management is a joke. Managers would make inappropriate sexual jokes, mock religious beliefs, not show up to meetings, and give unreasonable deadlines. Like being told on Friday afternoon something needed to be done by Monday.
There is no training or job-specific onboarding at all. I was given a google doc and was essentially on my own.
Unless you wanted to drink and play ping pong in the basement all day you got short shafted. Your best bet for promotion in this place is to be a "bro".
Yet other teams like the poor folks doing Salesforce have to work mandatory overtime and have been doing that for the better part of a year due to yet again the failings of management. I'm not talking 5 or 10 hours either, 20 plus. (I heard that exact number from 3 of the developers I was friends with on that team).
