The Wintermute Interview Process for Crypto Trading Roles

Wintermute hires year-round rather than on a campus calendar, and the process tests market-making mechanics against a market that never closes.

Wintermute is a crypto-native market maker headquartered in London that hires on a rolling basis throughout the year rather than around a fixed graduate calendar, and its interview process, typically four rounds, tests the same core market-making mechanics as a traditional options or futures firm while adding questions specific to digital asset market structure: exchange fragmentation, on-chain settlement, and the fact that the market it quotes never closes.

Because crypto markets trade continuously across a fragmented set of centralized exchanges, decentralized exchanges and on-chain liquidity pools, Wintermute's trading and research roles require comfort with market structure concepts that do not exist at a traditional equities or futures desk: gas costs, block confirmation times, and the mechanics of automated market maker pools alongside standard order book dynamics. A candidate who has only studied traditional limit order book mechanics should extend that reading to cover how liquidity provision differs on a constant-product automated market maker before interviewing.

Because the firm was founded in 2017, well after most of the systematic funds and market makers in this guide, its hiring process has less institutional ceremony: fewer rounds, faster turnaround, and a willingness to make an offer within one to two weeks of a first interview for a strong candidate, which is unusually fast for a firm of its size.

The process typically opens with a recruiter call followed by a technical test covering probability, quick mental arithmetic, and a coding exercise in Python. The arithmetic component is timed tightly, similar to what a traditional options market maker tests, and candidates benefit from the same kind of preparation: repeated timed drilling on practice rather than untimed reading.

Because crypto markets trade at higher realized volatility than most traditional asset classes, interviewers sometimes ask candidates to reason about position sizing and risk limits under conditions more extreme than a candidate might expect from equities or rates experience, and the site's guide to the Kelly criterion is useful background for that line of questioning.
