The process took 4 weeks. I interviewed at Flow Traders (New York, NY) in Sep 2016
Interview
Webcam Interview (to check if you can speak English without an accent most likely)
Online Math and SAT-type Exam (on different days)
HR Behavioral Phone Interview
Onsite Trading Case
Easily the easiest trading interview process, but it's still hard. Absolutely amazing firm, they are a public company so you should go dig into the financials yourself. I turned them down because I am crazy.
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
