I applied through a recruiter. I interviewed at Xantium (London, England) in Sep 2025
Interview
The process was very smooth overall. The interviewers asked questions on probability, statistics, linear regression, and some programming. The questions focused on fundamentals and problem-solving rather than anything too tricky.
Standard QR interview, on statistics like linear regression and basic questions. I suggest future candidates to recap fundamentals like correlation, covariance matrix. Also resume questions were asked in some depth.
