I applied online and had a call with a talent partner (3rd party from what I could understand). It was a Zoom call, about 30 mins. We discussed the company and the role and I was asked some questions
Interview questions [1]
Question 1
How would you describe something technical to a non-technical customer?
How would you handle an irate customer and communicate the urgency to engineering?
First HR will contact you, then if you are good fit an hour of technical round interview with 2 engineers from the team. They focus a lot on the math behind ML including the derivates of loss function and chain rule. Be prepared to be interviewed from PhD students which cares a lot behind the theory and not the actual technical skills.
I applied through a recruiter. The process took 3 weeks. I interviewed at DeepL (London, England) in Apr 2026
Interview
- a call with the recruiter
- a mostly informal conversation with the hiring manager, where I had a chance to learn more about the role, what they are wanting to build, how they work as well as talk about my experience and answer some technical questions
- a recruiter call to go over feedback
- a technical deep dive with a panel of senior engineers
