Spotify Data Scientist Interview Rounds

Round 1- Recruiter Phone Screen

This is a general call with the recruiter and is mostly non-technical. This round lasts around 30 minutes and focuses on if you are a good fit for the role and the company. This is mostly an informal discussion about your experiences, resume and past projects.
