The 5 questions you're bound to be asked in a Wall Street internship interview

You know how competitive Wall Street internships are - so if you land an interview with a bank, you want to come prepared.

To help you out, we spoke to a former analyst at a bulge bracket bank who's been through the whole process first-hand.

He told us the five most common technical questions he encountered in investment banking intership interviews.

The good news is, each question is answered in-depth in the Mergers and Inquisitions "Breaking into Wall Street" guide.

"Don't waste your time with any other prep services," the analyst said.

He recommended studying all the "basic" level questions from the M&I guide in addition to these five questions. (If you're pressed for time, don't need to worry about the "advanced" questions, he said. They're not as essential for internship-level interviews.)

We got the answers from Mergers and Inquisitions. If they make no sense to you and you want to work on Wall Street, you've got some background reading to do.
