I applied through university. The process took 4 weeks. I interviewed at Flow Traders (Boston, MA) in Oct 2016
Interview
The process starts with a typical behavioral interview. Initially, the interviewer asked questions about my skillset and education. Then there were some behavioral questions like "Tell me about a time were you had to think out of the box". In general, the whole process was very professional. The second round was a math test (similar to the tests that can be found on tradertest.com). The third round was a logic test. After that its just a trader case. Did not make it to the last two rounds unfortunately.

Question 1
Tell me about a time were you had to think out of the box
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
