❓ Real Supabase Interview Questions & Hints

Question 1 • Database Architecture

“How does Row Level Security (RLS) work in PostgreSQL, and what are the performance trade-offs?”

💡 Recruiter Hint & Strategy:Explain security barrier views, index utilization, and query plan impacts.

⭐ Model Answer Structure:RLS evaluates security policies as filter predicates directly in the query plan for every row. While secure, policies with complex subqueries can prevent index scans. We optimize by indexing foreign keys used in policy checks and using stable JWT helper functions.

Question 2 • Behavioral

“Why do you want to contribute to an open-source company like Supabase?”

💡 Recruiter Hint & Strategy:Talk about community involvement, public documentation, and transparency.

⭐ Model Answer Structure:I believe open-source infrastructure is the foundation of the modern web. Building tools that empower thousands of developers in public with open feedback cycles aligns with how I build software.
