| # Quant interview questions with numeric answers | |
| Here you'll find 241 questions like the ones candidates meet when they apply for quant trading and research roles. Most are probability puzzles and brainteasers, though a few on expected value and market making are mixed in. Whatever the question, the reply it calls for is a single figure. | |
| Because of that, the set may turn out more useful than you'd expect. Nobody has to write out an explanation, so you can treat the collection as a small mathematics benchmark and mark a model automatically with a tolerance check. | |
| A row holds an `id` and a `topic`, a `difficulty` label (easy, medium or hard), the `question` in plain text and the `answer` as a numeric value. Fractions are written as decimals to ten places. With that in mind, I'd mark with a tolerance of about 1e-6. Worked solutions sit behind the link in the `worked_answer` field. | |
| Code computed and checked the answers when they first went into our question bank. While preparing this upload I also reworked a handful by hand, and the one-pair poker hand is a good example: it comes to 1,098,240 hands out of 2,598,960, or about 0.4226. | |
| If you're getting ready for quant interviews yourself, you'll probably find the questions easier to learn from on the site, where they're timed and all the solutions are written out in detail: https://geodesicpartners.co.uk/quant-questions-probability | |
