Flow Traders interview: what candidates actually report
Flow Traders discussion is short and repetitive, which is itself informative: nearly every account leads with numeracy under time pressure, and the rest of the process is described as conventional by comparison.
This page summarises what candidates have publicly and repeatedly described across forums over recent cycles. It quotes nobody and reproduces no thread; the discussions are linked below so you can read the primary sources yourself. QuantPit is independent and unaffiliated with Flow Traders. Processes change between cycles, roles, and offices, so treat this as a map rather than a schedule, and let your invitation email and the firm's careers page overrule anything here.
What candidates agree on
Reported consistently enough across cycles that you can plan around it.
A numerical test under time pressure comes first
Candidates describe timed arithmetic and numerical reasoning as the opening filter, with the same speed emphasis reported at other Amsterdam-headquartered trading firms.
ETF and market-making basics come up
Because the firm is known as an ETF market maker, candidates frequently report questions about how market making works, why spreads exist, and how a quoted price relates to underlying value.
Interviews are practical rather than academic
Reports describe conversations about trading intuition and mental arithmetic more often than deep theory, relative to research-heavy firms.
Motivation questions carry weight
Candidates commonly describe being asked why trading and why this firm specifically, with generic answers landing poorly.
What candidates disagree on
Where accounts genuinely conflict. Anyone stating these confidently is generalising from one data point, their own.
The exact assessment format
Descriptions vary across cycles and offices, including different platforms and question mixes. Your invitation is the authority.
How much product knowledge is expected
Some candidates report needing to explain what an ETF is and how creation and redemption work; others report none of it. Knowing the basics costs an hour and removes the risk.
Reported timeline
Reports commonly describe a few weeks end to end, with the assessment arriving quickly after applying and interviews following in short succession.
Read the discussions yourself
Live searches rather than links to individual threads, so you see current reports rather than a snapshot from an old cycle.
Common questions
What is the Flow Traders assessment like?
Candidates describe a timed numerical test emphasising speed and accuracy under pressure, in the same family as other Amsterdam trading firms' arithmetic screens.
Do you need to know about ETFs for Flow Traders?
Reports vary, but the basics are worth an hour of your time: what an ETF is, why its price tracks a basket, and how a market maker profits from quoting both sides.
How do you prepare for Flow Traders interviews?
Daily timed mental arithmetic, market-making fundamentals including spreads and adverse selection, and a specific answer to why trading and why this firm.

Reading about it is not preparing for it
The threads tell you what the test looks like. Sitting one tells you whether you would pass it.
