I applied online. I interviewed at DeepL (New York, NY) in Apr 2026
Interview
1. Recruiter Screen
2. DSA round - mine as data structure design
3. AI Round + System Design rounds. system design was basically design DeepL api. AI Round was more about product management and scoping work instead of ai rounds at meta/shopify.
4. I think they have a cultures interview. I didn't get this far.
They seemed really invested in a single approach on the system design round. less of system design, more just general trivia than the system design taught on hello interview. ai round was unclear on how it was scored.
Interview questions [1]
Question 1
design deepl translation service. how would you plan work on this repo and use ai to write tickets for it. design this specific cache data structure.
After initial recruiter screening there was live coding session in .Net to implement DFS in Google Docs - no IDE. Hiring manager was providing hints when stuck. Very cooperative atmosphere
Application followed by a link to schedule a chat with a recruiter a day later, chatted with the recruiter and discussed various aspects of the company. Would have been followed by technical interviews but I withdrew at this point.
