I applied online. The process took 2 weeks. I interviewed at AKUNA CAPITAL in Sept 2016
Interview
1. Hackerrank coding challenge. Five questions in 90 minutes. Varied in difficulty. Make sure you read all the questions and plan accordingly.
2. Phone interview. Talked about resume and projects. Then moved on to 10 conceptual questions. Common OOP concepts and Python things. The interviewer was patient. I should definitely have touched up on my conceptual questions... Froze up a few times but interviewer was mostly helpful.

Interview
All the interviewers I talked to were disinterested to a point where they were downright rude. With trading being a competitive industry, if they can't even find interviewers with a hint of enthusiasm for their company I'm not sure how they can convince anyone to join them.
OAs are tough, but if you can get most of the tests to pass you'll get a phone screen I think. It might take a long time to schedule, but phone screens have coding (not LC) or just CS fundamentals trivia depending on the team.
