I know summers will pick up on/learn a bunch of stuff (eg. more practice area-specific information) over the summer, but what are some basic things we should know about firms coming in? Their overall functioning, general practice areas, lunch etiquette? Is there a basic finance background we should have? At minimum, it would be cool to understand the associates/partners when they tell me about their work (back during interviews, I had no idea what they were talking about

Thank you!
