UBS Interview Questions
A representative practice mix for UBS quant analyst and strategist interviews: probability and EV, options pricing and hedging, statistics, and classic brain-teasers.
Inside the UBS interview
UBS is a global investment bank and wealth manager whose quant analyst and strategist seats sit close to derivatives desks. Interviews emphasize probability and expected value, options pricing and hedging, and applied statistics, with classic brain-teasers to test clean reasoning under pressure.
What they test
The core is probability and expectation — conditional reasoning (Monty Hall, Bertrand’s box, posterior updates) and optimal-stopping / EV puzzles like the secretary and three-roll dice games. Around it sit options pricing (binomial trees, put-call parity, Black-Scholes from a risk-neutral expectation) and statistics (MLE, the German tank problem, Simpson’s paradox).
The recurring shapes
A recurring move is the risk-neutral expectation: price a derivative as the discounted expected payoff under the risk-neutral measure, then check it against a no-arbitrage relation like put-call parity. Expect to set up and solve these from first principles.
How to approach
State assumptions out loud, build the smallest model that captures the payoff (one-step binomial before continuous time), and sanity-check with parity or a boundary case. For the brain-teasers, find the invariant or the clean recursion before reaching for arithmetic — interviewers grade the reasoning, not just the number.
The difficulty spread runs from a few easy warm-ups through a medium core to several hard derivations, mirroring a real UBS quant loop.

UBS interview FAQ
What kind of questions does UBS ask in quant interviews?
Candidates most often report probability, expected value and options pricing questions. This page collects 24 of them, 5 stamped with the month they were last reported — each with a full worked solution.
How hard are UBS interview questions?
The set spans 9 easy, 11 medium and 4 hard problems. Most sit at medium difficulty — solvable in a few minutes with clean reasoning — with a harder tail that rewards knowing the canonical tricks.
How do I prepare for the UBS quant interview?
Work through this set by topic (use the sidebar), starting from your weakest area. 12 problems are free to open with their full solution, so you can judge the quality before anything else. Then broaden out with the related firms below — the question families overlap heavily.
Are these the actual UBS interview questions?
They are built from candidate-reported UBS questions. We rewrite each prompt for clarity and author the worked solutions ourselves — we don't claim the wording is verbatim, and we never invent questions or recycle generic lists. 5 of 24 carry the month they were last reported.
