Common Screening Mistakes

Fixating on a specific programming language when the role allows flexibility — backend patterns (API design, database modeling, auth) transfer across languages, so a strong Python developer can learn Go on the job
Not asking about database experience beyond 'I used PostgreSQL' — the difference between a junior and mid-level backend developer often comes down to whether they can design schemas and optimize slow queries
Dismissing candidates without cloud certifications — practical hands-on experience deploying to AWS matters more than a cert; ask about what they've deployed, not what exams they passed

Red Flags

Cannot explain how a REST API works at a basic level (HTTP methods, status codes, request/response cycle) — this is foundational knowledge that any backend developer should have internalized
Has never thought about database indexing or query performance — even at the junior level, awareness that queries can be slow and indexes help is a minimum bar
Describes all past work as solo projects with no collaboration — backend development requires tight coordination with frontend, DevOps, and product teams

What Good Looks Like

A strong backend developer candidate explains their past work in terms of data flows and system interactions — not just lines of code.
They can describe how they designed an API — what database trade-offs they considered, and how they handled error cases.
They show curiosity about your system architecture during the interview.

Key Tech to Listen For

RESTful API design and HTTP status codes
SQL joins, indexes, and query plans
ORM vs. raw SQL trade-offs
Authentication flows (JWT, OAuth)
Docker containers and environment management
Caching strategies (Redis, CDN)
