I applied online. The process took 8 weeks. I interviewed at IMC Trading (Sydney) in May 2017
Interview
Multiple stages, first is a 3 hours coding test of 3 questions. Then aptitude/numeric test + personality test, followed by video interview and then an on-site interview consisting of a coding station (laptop) and problem solving station (white board). If you pass this you get invited to a super day that is similar to the first on-site, if you make it through the superday you get an offer.

for online assessment, there was a question about calculating info from an order book. helps if you know how one works beforehand. only one question and coding preferred in C++ or java.
one technical round and one hr round. technical round was moderately hard. hr round was about your personality, asking about general questions to check if you fit in their workspace.
Coding Challenge, Recruiter Phone Screen, Project Interview, Onsite. Coding Challenge was definitely on the challenging side of those I've taken. They dive deep into your past & current experiences for project interview. Onsite was challenging -- a long problem statement.
