Invited for a mental math test and a verbal logic test. Mental math test is pretty similar to the sample test posted on their website. Rejected after the logic test.
I applied online. The process took 6 weeks. I interviewed at Flow Traders (Amsterdam) in Mar 2020
Interview
Multiple stage interview process, similar to every other quant role with generic brainteaser questions. The interviewers were very friendly and helpful, and quite clear on the brainteasers. Big on company ethos and work ethics.
Interview questions [1]
Question 1
First interview stage requires fast arithmetics, second is behavioural, and then a series of technical interviews afterwards followed by an in house day.
