A Goldman Sachs insider has posted a survival guide for the firm’s summer interns — urging the newbies to name-drop, tell racist jokes and hook up with their female colleagues.

The man behind popular Wall Street gossip blog GS Elevator welcomed the interns to the competitive program by reminding them, “You’ve been vetted and hired by Goldman f–king Sachs.”

“You might feel like you just crossed the finish line,” he wrote. “But the race hasn’t even started yet.”

He then lists 20 tips to help interns land a full-time job — including prissy fashion advice and when to suck up without being obvious.

His advice:

* “Bang a [female] intern, and tell the associates and above about it. If they haven’t ever done it, they sure as hell always wanted to. They’ll respect you for it.”

* “Always repeat racist jokes in the proper company and be sure to credit ‘the other intern’ who told you.”

* “If you went to a decent boarding school, subtly find out if anyone who matters went to the same school.”

* “Don’t wear Hermes ties, ever. You have to earn it.”

* “If your boss is Indian or Pakistani, learn the rules of cricket.”

He finishes by assuring interns not to worry if they don’t get hired.

“Not making the cut at Goldman is like being traded by the Yankees. You’ll still probably make millions,” he writes.

The author created a splash earlier this year when he began blogging about conversations overheard at the firm.

He now has nearly half a million Twitter followers and rakes in up to 5,000 hits on his blog per day, he said.

He told The Post he expects interns to find and read the advice on Twitter.

“It is exceptionally cutthroat, more now than ever,” he said.

“That’s because banks do most of their recruiting from the intern pool. So everyone is fighting to ‘get the offer.’ ”

He added, “If you don’t get the offer, you have to explain in every future interview why you didn’t get an offer,” he said.

On the blog, he also notes that it’s “impossible to compete” with female interns and that it’s important to keep your shoes shined.

Avoid wearing pleated pants, when possible, he adds. Only 350 college students — out of 17,000 applicants — were accepted to the firm’s Summer Analyst Internship.

A Goldman spokesman said he has no idea who the blogger is.

“He sounds like an investment banker from the ’80s,” he said.
