Overview

Supabase interviews reflect their identity as the open-source Firebase alternative. The coding difficulty is moderate (58% medium), and the process values open-source mindset, PostgreSQL expertise, and full-stack engineering. As a smaller, fast-growing company, Supabase interviews are less formulaic than Big Tech. Expect conversations about database internals, real-time subscriptions, and developer experience alongside standard coding rounds.
