I applied through college or university. I interviewed at AKUNA CAPITAL (Chicago, IL) in Dec 2017
Interview
four round,
1. online mental math test (sequence pattern and basic math).
2. online coding python test time limit 120 minutes.
3. phone technical interview with both trader and quant dept (2 rounds) .
4. onsite interview(2-4 hours onsite in chicago).
I was selected for numerical testing and then first interview. Basic competency based questions including machine learning and computer science. Focus on quantitative ability. Was a good experience overall with feedback.
Phone interview with expected value probability question. Interviewer is helpful and nice. Question was very unclear at first, so ended up messing it up, but interviewer was giving helpful hints.
I applied online. The process took 4 weeks. I interviewed at AKUNA CAPITAL (Sydney) in Jun 2020
Interview
First stage was a quick maths and sequence test. Some of the questions got hard towards the end to answer quickly eg. 124x57. 2nd Stage was a coding challenge where they asked you to complete 3 coding questions in 1hr. I only managed to finish 1 and a half but still made it through to the phone interview which I have not completed yet.
