I applied through a recruiter. I interviewed at Avanti Recruitment (London, England) in Jan 2026
Interview
The interview process consisted of an initial phone call with a recruitment consultant. During the call, I was asked a few general questions about my background, experience, and availability, and I provided brief answers.
Interview questions [1]
Question 1

What was the mathematical foundation, how did you implement backpropagation, and what optimization challenges did you face?
