I applied through college or university. The process took 4 weeks. I interviewed at Flow Traders (New York, NY) in Oct 2016
Interview
The first-round interview consists of 10-min mental math session followed by 20-min behavioral questions conducted by an HR representative. The second-round is an aptitude test that is done online. Final round took place in Flow Traders' NYC office and consists of a quick session with the HR representative, a case study on ETF trading strategy followed by some general behavioral questions with two traders.
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.

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
