I applied online. I interviewed at Photoroom (Berlin) in Jun 2026
Interview
The recruiter contacted via email. Short initial screen with the recruiter. And then a technical interview with the hiring manager.
There were no certain technical questions; the hiring manager asked about my background, achievements, and expected STAR method answers. At the end, there were questions about the values of the company.
The technical questions included:
- (After I mentioned a couple of public APIs I worked on) The rpm of the endpoints, the high-load ones
- What was the metric leading into scaling of these APIs?
- What metrics to judge the performance? Response time, P99, P90, those kinds of things
I'd suggest getting ready with concise examples where you succeeded, failed, got some feedback, and changed your behaviour. And also, they are most probably looking for someone not at the Senior level, but at the Staff level, with a super strong focus on FastAPI - still no questions about concurrency, async Python, workers, etc. during the interview.
