How it went
The interview process at Mercor for a Data Scientist role was challenging, requiring candidates to deeply explain past projects and justify technical decisions. The day-long on-site involved several components: a SQL assessment with medium-difficulty problems, an analytics exercise using Python with messy data and AI tools, a modeling strategy discussion, and a product sense interview.
