Weird and difficult interview questions asked by top hedge funds
Interviewing with a top hedge fund is not dissimilar to interviewing with Goldman Sachs: you'll usually be expected to attend multiple rounds of interviews and the process might be stopped at any point. But while Goldman Sachs has all but given up asking brainteaser style interview questions, hedge funds are still fully committed to putting people on the spot. They may also ask you to sign a non-disclosure agreement to never talk about your interview once it's over.
Based upon the questions recent interviewees nonetheless say they've been asked on Glassdoor, Wall Street Oasis and other sites, hedge funds' interviews can be challenging. Here's a sample of what you'll need to be ready for.
1. The probability you'll see a falling star in the sky over the course of one hour is 0.44. What's the probability you'll see one over half an hour? (Asked by Citadel)
2. You are given two ropes that when lit burn in one hour. Which one of the following time periods CANNOT be measured with your ropes? a) 50 min b) 30 min c) 25 min d) 35 min. (Asked by Citadel)
3. You have three cards, each labeled n, n+1, n+2, and you don't know n. All cards start facing down so you can see them. You flip one card. If you choose to "stay", you get that card's value. If you don't "stay", then you flip another card. Again, choose to "stay" (and keep the 2nd card's value) or flip the final card and keep the final card's value. Design the optimal strategy to maximize the value of the card that you choose and find the expectation of that value. (Asked by Citadel)
