I applied through college or university. The process took 1 week. I interviewed at Susquehanna International Group
Interview
Interviewing with SIG is the worst interviewing experience that I have ever had. They seem to be totally uninterested in hiring. They will send a reject email without even evaluating your interview results. Though you do well you are most likely to get a reject email.
