I applied online. The process took 2 weeks. I interviewed at Flow Traders (Amsterdam) in Nov 2023
Interview
Good process, first round is mental calculation test, train a bit but not that hard.
Then interview with HR easy as well and interview with trading is where things get harder
Interview questions [1]
Question 1
You have 1000 bottles of water, one of which is poisoned. You have a bunch of lab rats that you can use to test the water and try to figure out which bottle is poisoned. Unfortunately, since the poison takes 24 hours to activate, and you must figure out the results in 24 hrs, you must feed all your rats now, and then wait the next day to see the results. How many rats do you have to use to figure out which bottle of water is poisoned?
Few Behaviorial Questions + Mental Arithmetic questions probability questions.
Final interview was pretty complicated for someone without a lot of experience asked a lot about etfs and stuff. They will ask you to think until you get the right answer
Application
I applied online. I interviewed at Flow Traders (Amsterdam) in May 2026
Interview
In ronde 1 moest je zowel een mental math test als sequences test maken. Ronde 2 is een standaardgesprek met een HR manager die je vraagt naar je motivatie en interesse in financiele markten en 1 simpele ETF brain teaser geeft. Ronde 3 is een technisch interview met een trader die eigenlijk compleet in het teken staat van elke keer in korte tijd een statistiek vraag of wat complexere financiele markt vraag te beantwoorden
