Let me just say first off that this will not be an exclusive thread to the Big 4, I simply have to appease my SEO fanatic co-workers. That means if you're interning at Grant Thornton, BDO, McGladrey, Moss Adams, Rothstein Kass, it doesn't matter, don't be afraid to jump in with questions or comments or respond to any of the regular commenters out there ("GT Partner" is a treat).
Anyway, it's not technically summer but DWB encouraged me to drop an open thread on you all so that A) interns can share their skyrocketing anxiety and B) the veterans can bestow some of their wisdom upon these coffee gophers so that they don't get in the way too much. Since I saw my fair share of interns pass through my time inside the House of Klynveld, I'll jump in first.
For starters new interns, you need dress nice. If you show up in baggy Dockers without a belt and a Nike golf shirt and scuffed-up shoes - I hate you already. And unless you can do back flips (as it relates to your work) and buy me coffee once a week, my mind is made up about you already. For the ladies, since the dress code is a little more subjective for you, all I ask is you not show up in your pajamas. That said, your female superiors will be eyeing your attire much closer and they will be judging the shit out of you. And if they're really offended by your fashion forwardness, they aren't above tattling on you. Believe me, I've seen it happen.
As for work - find it. Sometimes you may have to act busy by reading god-awful training manuals or diversity literature or something else that makes you want to bathe with a toaster but FOR THE SAKE OF YOUR MEDIOCRE BIG 4 CAREER, I suggest you don't look bored. I don't care if you have to grovel to the lowliest A1 on your team, if you're not working (or at least appear to be working), someone will notice and that doesn't bode well for your chances at fulltime offer.
Finally, make some friends. Can you carry on a conversation that doesn't revolve around your Beta Alpha Psi chapter or the bitch of an Intermediate mid-term you had? Excellent, you'll be fine. Someone will like you. If you like talking about those things, I strongly suggest you find a hobby fast. The Mets are driving you crazy? Great, talk about that. You just saw the Arctic Monkeys in concert? Wonderful, music is rad. Outdoorsy type? Talk about some camping trips. You're into Brazilian Jujitsu? Okay but don't show off your injuries. That's just gross.
Bottom line: be yourself. Unless yourself sucks. In which case, email the career advice brain trust and we'll turn this around. Now if you'll excuse me, some of us don't have interns and I have to fetch my own coffee.
