I applied online. I interviewed at Susquehanna International Group
Interview
16 question aptitude test with Maths / Logic based Questions followed by a possible Three Interviews, the first two of which are over call or zoom, the last of which is in person in SIG's IFSC HQ and consists of a tour and interview. First interview is 80 / 20 Maths to Generic interview questions, second one is more 50 / 50, more talking about your CV and why you want to work there. The last one is more of the same, EV and Mathematical logic questions and then talking through your CV. All staff were extremely professional and the perfect blend between polite and friendly while still being confrontational and serious enough to conduct a tough interview.
The process included an OA followed by a phone call. The CodeSignal had four questions: two easy and two medium. Overall, it was average difficulty, with matrix familiarity especially useful.
