I applied online. The process took 2 weeks. I interviewed at Susquehanna International Group (Philadelphia, PA) in Mar 2017
Interview
There was an initial phone screen followed by another phone screen then they brought me to the office.
My biggest impression I got was that they didn't know what they wanted and they were unprofessional.
They brought us into a dim top level office where we had to code on very slow computers. We had 45 minutes. Nothing was setup and I spent 20 minutes fiddling with the IDE.
After that were 3 rounds of "interviews" each with two people. The first was super unprofessional and kept eating his nails in front of me. The rest were just "explain this on your resume". It was stupid, and then maybe one guy would ask some trivia about the language you did. It wasn't structured.
Watch out for the telltale signs that you'll be overworked.

I applied online. I interviewed at Susquehanna International Group
Interview
The OA consists of four LeetCode questions, needed to be done within 70 min. Highly recommend revising how to do the int-string conversion in the language you will use. The problems themselves are not hard, but better to have a clear high-level view before you code.
