I applied online. The process took 2 weeks. I interviewed at Susquehanna International Group (Bala Cynwyd, PA) in Sep 2017
Interview
Three stages. General HR phone screen, technical phone interview, 5 hr in-person interview with multiple interviewers and a technical assignment. Interviewers were generally nice and personable. Three pairs of interviewers, each approximately an hour long.

Question 1
Technical assignment included a problem in which you read data from a csv file, then used the data to calculate gas mileage with various filters (owner, time window, etc).
I applied through a recruiter. I interviewed at Susquehanna International Group (Dublin, Dublin)
Interview
Was pretty easy, 1 round of phone screen interview + 2 - 4 hours of onsite final round. Onsite is scheduled to take place in person in the office.
Interviews were pleasant to talk good and experience was quite good.

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.
