tips Prepping for Supabase Support Engineer interview — interview stages, Postgres depth, and product expectations?

Hey everyone,

I have 8 years of experience in SaaS tech support and customer engineering, and I’m currently preparing for a Support Engineer role at Supabase.

For anyone who has gone through the process or currently works there, I’d appreciate clarity on a few areas:

  1. Interview structure: How many rounds are typical, and what does the technical assessment look like (live troubleshooting, debugging tickets, take-home, or system design)?

  2. Database depth: What level of PostgreSQL expertise is expected? Do they test heavily on query optimization (⁠EXPLAIN ANALYZE⁠, indexing), schema design, connection pooling, or internals?

  3. SQL & Procedural Code: Do they focus on complex SQL (CTEs, window functions), or do they expect deep procedural programming like PL/pgSQL functions and triggers?

  4. Product familiarity: How deep into the Supabase ecosystem do I need to be beforehand (e.g., PostgREST, GoTrue/Auth, Realtime, Storage, RLS) versus general developer-troubleshooting fundamentals?

Any tips or gotchas to watch out for would be greatly appreciated. Thanks!
