I applied online. The process took 3 weeks. I interviewed at IMC Trading in Sep 2018
Interview
The first part of the interview process included a 90 minute coding challenge, followed by two phone interviews depending on how well you did on the coding challenge. It is highly recommended that you get a lot of practice from Leetcode or similar platforms, before taking the coding challenge, as time is quite constrained if you consider debugging.
