Which competencies define a reliable django competency checklist for hiring?

The competencies that define a reliable django competency checklist for hiring span framework fluency, Python depth, databases, web APIs, testing, security, performance, and delivery operations. These domains anchor evidence-based evaluation against production duties.

1. Core Django framework mastery

• URLs, views, templates, forms, admin, apps, middleware, settings, and project layout form the base.

• Request–response flow, class-based views, and context rendering drive clean endpoints.
• Form validation, CSRF, and sessions sustain safe, stateful user flows.
• Pluggable apps, signals, and middleware enable cross-cutting policies and extensibility.
• Settings per environment, allowed hosts, and env vars keep configurations reliable.

2. Python language depth for Django

• Data structures, OOP, typing, iterators, decorators, and context managers shape maintainable code.
• Memory, concurrency primitives, and packaging hygiene raise reliability and speed.
• Idiomatic constructs reduce cognitive load and enable faster reviews.
• Type hints and linters limit regressions and raise refactor confidence.
• Async features, multiprocessing, and queues unlock throughput under load.
• Poetry/pip-tools, venvs, and reproducible builds keep environments consistent.

3. ORM and database design expertise

• Model design, relations, migrations, and query optimization govern data integrity.
• Indexing, transactions, isolation, and connection pooling secure correctness and speed.
• Normalization vs. denormalization choices balance performance with clarity.
• Query plans, select_related/prefetch_related trim N+1 issues at scale.
• Schema migration safety nets ensure zero-downtime delivery across versions.
• Observing slow queries and tuning indices sustains predictable latency.

4. HTTP, REST, and API integration

• HTTP semantics, status codes, idempotency, and caching models underpin stable APIs.
• Django REST Framework patterns shape discoverable, secure interfaces.
• Consistent serialization and pagination support scalable clients and UIs.
• Auth flows with sessions, JWT, or OAuth safeguard data access.
• Rate limits, ETags, and conditional requests manage load peaks cleanly.
