A timed mental-math and sequences test with negative marking, then ETF/ETP arbitrage reasoning under deliberate interviewer pressure.
Flow Traders makes markets in ETPs/ETFs (and crypto ETPs). Its numerical test is the notorious filter, reported around 60 questions in 6 minutes with negative marking, one question at a time.
Later rounds test ETF mechanics (creation/redemption, arbitrage, leveraged decay) and composure under staged pressure.
