I applied through an employee referral. The process took 2 months. I interviewed at Susquehanna International Group (Bala Cynwyd, PA)
Interview
Day-long interview comprised of meetings with four teams of two and concluding with a session with the senior manager of the group. First part of the interview is a 60-minute test (which is impossible to complete) containing 12 coding problems. Remainder of the interviews include extensive whiteboarding of solutions to problems posed by interviewers.
Interview questions [1]
Question 1
Define a solution architecture for a system handling a high volume of transactions.
Overall process is fine. The main problem they didn't respond to my email after the final interview.
- interview with Hiring manager about experience related to the job
- on site interview with several python questions and simple leetcode task + system design task
I applied through a recruiter. I interviewed at Susquehanna International Group (Dublin, Dublin) in Jul 2025
Interview
The online stages were pretty simple given my seniority (15+), and the online interview was nice. You have to implement tickers lookup by the headline, mentioning the company names. As fast as possible of course.
