25 Things Every Wall Street Intern Should Know

Now that Fourth of July weekend is behind us the summer is in full swing, your interns are finally getting settled in. In fact, they've probably adjusted to the good natured hazing they've experienced on the trading desk — like testing their resourcefulness by asking them to bring you a root beer float. Perhaps the time is right to sit them down for a little heart-to-heart chat about the perils and opportunities that lie ahead of them. With a little time and effort, you can be their Virgil in Wall Street's underworld: The Internship. By Ash BenningtonPosted 5 July 2011

Asking strangers for money on the phone is probably the worst thing you'll do in your career, but it builds tenacity and forces you to develop an enormous tolerance for rejection. If you're perceptive, cold calling will teach you the one sacred truth you need to succeed in this world: Life is a straight-up numbers game, baby.

When they talk to you, an intern, they don't actually expect you to speak to them in return. You just need to listen and nod attentively—like you're hearing the great riddles of the universe solved for your benefit. This may sound demeaning but it isn't. Not having to talk much or commit to anything is one of the biggest benefits of your internship.

Your boss may have no idea how he's going to cover the 40K he owes American Express next month—but it will make him feel better about his own situation to peel off a dozen twenties and hand them to you. To him, it's literally taxi fare: To you, it's a month's worth of groceries.

Yeah, it's a little more expensive than shopping in a discount grocery store. But—and trust me on this—you'll never actually make it to a discount grocery store.

Especially when you're really hungry. The problem is this: As far as I know, no one under thirty has ever left Brother Jimmy's after one beer and a burger. By the time last call rolls around, you'll have blown through your food budget for the week. (Really, trust me on this.)

Dude, pony up and move out of your mom's basement. There are lots of desperate people on Craig's List who are stuck with huge rents they can't cover by themselves—and that's a major opportunity for you. You don't want to be the person who always has to leave early to catch the last train back to Jersey.

Then, you stay in the city for the first few weekends in July—and make them feel really guilty when they tell you how awesome their weekend was. The beauty is this: When you start showing up at the beach later in the summer your friends will actually be thrilled to see you. Best of all, it will be free. Just bring beer—nobody likes a freeloader.

Even if you come from one of the really polite sections of the country, like the South, you'll eventually adjust to it.Just stare at the sidewalk when you walk by anyone who looks like they may be conducting a survey or collecting signatures. (Note: You'll know when you've gotten it right when you're walking to Penn Station and you get ignored by the guys handing out discounted tickets to the Empire State Building: With enough practice, they'll know you're not a tourist from a hundred yards away.)

(No one will understand what it means—but that's ok because just about nobody really understands economics in the first place.)

Photo: Fuse | Getty Images In fact, if your boss tells you job titles are irrelevant he's almost begging you to call him on his bluff. Telling him it's total nonsense may get you fired, but you'll have the satisfaction of seeing his face when you suggest that he spend the next 12 hours staring at a pivot table while you head out to the Hamptons to play the back nine at Shinnecock.

Those who attended elite liberal arts colleges typically harbor no illusions about the practical value of their education.)

(Seriously, I think Julia La Roche is Facebook friends with every third intern on Wall Street: She's so plugged in it's scary.)

Photo: Peter Dazeley | The Image Bank | Getty Images As hard as this may be to believe, people are actually being nice to you. When you return as a first-year associate—and they're paying you real money— it will be a different story because then they'll own your soul.
