Backend screening is about trust: can this person build something that stays up, and do they understand what happens when it does not. Your resume should read like evidence of systems that survived contact with traffic.
Services designed, data models chosen, migrations run. Ownership of a system boundary is the clearest signal of backend seniority short of a title.
Requests per second, p95 latency, uptime, queue depth, error rate. Backend claims are unusually easy to make concrete, and vague ones are unusually easy to disbelieve.
Postgres, MongoDB, Redis, Kafka and the reasoning attached. "Moved session storage to Redis to remove repeated joins under load" demonstrates judgment, not just familiarity.
Deploys, retries, reconciliation jobs, manual interventions. Backend engineering value is often expressed as something a team stopped doing.
On-call, incident response, monitoring and alerting are what separate a developer who writes code from one who is responsible for it. That responsibility is what senior roles pay for.
Spring Boot or Express alone says very little. Pair it with the database, the queue and the deployment environment so a reader can picture the system you worked in.
Authentication, authorisation, encryption and compliance are heavily weighted and frequently omitted. If you implemented them, put them in plain language.
Systems that handle retries, idempotency and partial failures are worth more than systems that handle the happy path. Say what you did about the unhappy path.
"High-traffic application" means nothing without a number or a comparison. Even a range gives the reader something to calibrate against.
The language and framework the target role uses, the primary datastore, and one of caching, queues or orchestration. Depth in a coherent stack beats breadth across every backend technology you have touched.
State the number of services, your responsibility within them and how they communicated. If you worked on two services in a larger estate, say that — the precision is more credible than the word alone.
At a high level, yes: components, data flow and the constraint that shaped them. Detailed diagrams belong in the interview, not in a document that gets twenty seconds.
For senior and staff roles it is often decisive, because it proves you have lived with the consequences of your design decisions. Describe what you were paged for and what you changed afterwards.
Name them, and name one specific contribution — an index that cut a query from seconds to milliseconds, a schema migration run without downtime. Specificity is what makes the skill believable.
