I applied through a recruiter. The process took 2 months. I interviewed at Datadog (Paris) in Aug 2025
Interview
It was a long process because I spaced out the interviews to prepare them well. 1 screening, 1 coding interview, 2 ML related interviews and final Experiences and values interview.
Overall it was a challenging, well structured process. All interviewers were nice and asked good questions
Interview questions [1]
