I applied online. The process took 2 weeks. I interviewed at Optiver in May 2016
Interview
1st phone interview, then test on HackerRank, was supposed to follow up with a visit, but did not pass the test. However the interview was very smooth, and the recruiter was very engaging. Unfortunately I did not do very well on the HackerRank test, and did not get an offer.
