Lots of corporate jargon used, and some of the financial concepts can be tough to grasp depending on your field. A company this size also means that when you have an issue, you might have to find a few different people before you get to someone who can help, and you may have to submit tickets and wait on them in the process.
You also likely have on-call duties if you're an engineer, which can vary widely depending on your team's applications. No overnight on-call though, they're 12-hour shifts.
