I applied through a recruiter. I interviewed at Susquehanna International Group (Dublin, Dublin) in July 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.
