I applied online. The process took 4 weeks. I interviewed at Susquehanna International Group (Bala Cynwyd, PA) in Sep 2024
Interview
First round - phone round with recruiter, chill
Second round - technical round with 2 developers. Binary search question with followups (given infinite preprocessing time, how could you make this O(1))
Final round - 1 hr OOP, design a grocery store checkout (items, produce, coupons, receipt), 2x 30 min manager chat (standard behav, why SIG, "tell me about a time when")

Manager chats - Why SIG, what environment do you learn best/worst, tell me about a project
I interviewed at Susquehanna International Group (Sydney)
Interview
OA (code signal GCA, 4 questions 70 minutes) -> Recruiter call (30 mins) -> 90 min technical screen. Presumably after this point would be onsite/in-office interviews but didn't make it there.
Had to do work in Python in a live interview session. Talked with hiring manager about resume. Overall it was not too bad. The interviewers were nice throughout the entire process.
