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.
