I applied through a staffing agency. I interviewed at Flow Traders (New York, NY) in Jan 2014
Interview
Contacted by agent, then skype interview, then online interview screen with behavioral questions. Next is on site with behavioral, and math/logical test. Now I am waiting for the next step.
The behavior questions were just screening, prepare on why interested with this job, and why should hire you. very typical. We also went through resume, and other realistic questions, nothing really hard.
Interview questions [1]
Question 1
Multiple choice questions with the multiple digits multiplication or division. Including decimal numbers.
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.

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
