I applied online. I interviewed at Flow Traders in Jul 2019
Interview
Mathematical test, containing 30 easy questions, 30 medium questions, and 15 hard questions. Make sure you make no mistakes in the easy part and minimal in the medium part. Hard part answers are in a dropdown menu, so you have to click to see the answers for a question. Strategy for the hard part should be to look for the easy questions and answer those first, as time will probably not be sufficient enough to answer them all.
First was a mental maths test of roughly same level as Optiver 80 in 8. Then had a 1-1 interview with HR, did not pass as had not researched company well enough.
I applied online. The process took 1+ week. I interviewed at Flow Traders (Amsterdam)
Interview
I passed the online mental math test, then got eliminated in the second round which was an online interview with HR, where I was asked to play a market-making game in which I had no previous experience. Although it is a junior position, you are still expected to have plenty of technical knowledge.
Interview questions [1]
Question 1
Do you know any ETFs? How are they priced? Do you know the current market price of the ETF you mentioned? Let's play a market-making game with that ETF
First round - math test, second round with HR on behavior questions, then with trader and HOT on more technical questions, do not expect deep knowledge on ETF. In general, it was not in a very harsh environment
