Hiring Strategy

Interview Preparation

Common patterns that frequently appear in backend/fullstack engineer technical interviews.

• Interview Prep Overview — Index & preparation structure
• Hiring Process — Recruitment flow from apply to offer
• Live Coding & Pair Programming — Rate limiter, idempotency, distributed lock, concurrency
• Take-Home Assignment — Strategy, project structure, assessment checklist
• System Design — Payment gateway, exactly-once processing, saga pattern
• Go-Specific — Goroutine leak, context, race condition, channel patterns

Specific Problems with Solutions

• Rate Limiter — Token bucket + sliding window implementation
• Idempotency Key — Payment endpoint with idempotency guarantee
• Distributed Lock — Preventing double-spending with Redis
