Not a read‑once book – Practice drawing designs yourself.
Mock interviews – Simulate real time constraints (35–45 min per problem).
Focus on trade‑offs – Interviewers want to hear why you choose one DB over another.
Combine with flashcards – Review key components (consistent hashing, quorum, leader election).
