Thought I'd take a second to answer this question posted in the comments section - "how much work do u realistically expect an intern to get done?"
Well, if you can perform tasks that require common sense and logical thinking, that's good enough. We really don't expect you to dive into revenue recognition, and totally understand that interns have no prior audit knowledge since we've all started at the bottom of the audit pole. But when it comes to formatting something in excel, and performing other simple tasks like tying out numbers from one sheet to another, we'd expect you to do that, (as long as your seniors are half-decent at explaining tasks). If your senior can't explain how to fit a key into a lock, then it's on them.
Hope everyone's enjoying busy season so far!
