I applied online. The process took 1 week. I interviewed at Susquehanna International Group (Penn, PA) in Dec 2019
Interview
Applied and got the test within several days, if not the next day. Received email regarding the online aptitude test. Didn’t get pass the quantitative screening. Questions were mostly all on discrete probability, difficulty from easiest to hard.
Interviewers were not engaged at all, one spent the entire interview on his phone, very unprofessional given the prep for the interview.
Interview was a mix of competency, market knowledge and probably based maths questions
first-round Phone interview; the first time the interviewer canceled the interview very last minute and rescheduled another one. Mostly behavioral questions; some easy probability questions e.g, binomial tree; last 20 minutes; did not really offer a q&a time
The interview process was rather straightforward tho challenging. The first interview, they ask you about yourself and experience. The next interview is a riddle round. They ask you to solve 3 riddles. It was fun but definitely pretty stressful. Come prepared.
