I applied through a staffing agency. The process took 3 days. I interviewed at Susquehanna International Group (Phila, PA)
Interview
First HR will contact you on telephone and have first behavioral round. Then someone from SIG will call you to have technical telephonic round. Once cleared, you will invited on-site. There will be a coding test, followed by 2-3 technical rounds, and 1-2 behavioral and cultural fit rounds. Very well conducted interviews.
Interview questions [1]
Question 1
Parsing CSV file, Garbage collection, multi-threading, data structures, system design
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.
