Interview Questions to Ask Before You Hire a Backend Developer
Identify the right fit faster with these targeted technical and behavioral questions.
API Design & Protocols
REST vs gRPC - what’s the difference?
REST uses resource URLs and JSON over HTTP/1.1; gRPC uses typed protobuf contracts over HTTP/2 with streaming RPCs.
What is idempotency and why does it matter?
Repeated calls have the same effect; enforce via an Idempotency-Key and deduplicate writes server-side.
How do you version public APIs?
URL segments (/v2), header negotiation (Accept: …), or resource expansion. Choose one and keep deprecation windows.
Offset vs cursor pagination?
Offset is simple but slow at scale; cursors use stable tokens for consistent, fast scans under churn.
Data Modeling & Databases
Normalization vs denormalization - define each.
Normalization removes redundancy for integrity; denormalization duplicates data for read speed.
Surrogate vs natural keys?
Surrogate keys (e.g., uuid) are stable and small; natural keys encode business meaning but can change.
B-tree vs hash index- when to use?
B-tree supports ranges and sort; hash is O(1) equality only, no ordering.
Transaction isolation levels?
Read uncommitted, read committed, repeatable read, serializable—trade anomalies for concurrency.
Concurrency & Async
Concurrency vs parallelism-difference?
Concurrency interleaves tasks; parallelism executes tasks simultaneously on multiple cores.
Event loop vs thread pool?
Event loop multiplexes non-blocking I/O; thread pools run blocking work on worker threads.
What is backpressure?
A producer slowing to match consumer capacity; apply queues, rate limits, or flow control signals.
What is a deadlock and how to avoid it?
Cyclic lock waits; prevent with lock ordering, timeouts, and small critical sections
Architecture & Microservices
Monolith vs microservices- when to choose?
Monoliths ship fast, easy to debug; microservices scale teams independently but add ops complexity.
Saga pattern-what problem does it solve?
Coordinates distributed transactions with local commits and compensations across services.
Circuit breaker-define it.
A guard that trips after failures to stop calls and allow recovery, then half-open probes.
Service discovery-how does it work?
Instances register to a registry; clients resolve service names to healthy endpoints.
Caching & Performance
Cache-aside vs write-through?
Cache-aside reads DB on miss; write-through writes cache and DB together for freshness.
CDN vs reverse proxy?
CDN caches edge content near users; reverse proxy sits before services for routing and caching.
p95/p99 latency - what do they mean?
95th/99th percentile request time; tail latency users experience under load.
N+1 query problem - define and fix.
Many small queries per item; fix with joins, prefetch/batching, or aggregating reads.
Red Flags to Watch For
⭕ Can’t define idempotency or isolation.
⭕ Synchronous I/O; ignores queues, retries.
⭕ No backpressure strategy under load.
⭕ Missing observability, CI/CD, safe rollbacks.
Additional Interview Questions
Reliability & Observability
SLI, SLO, SLA-differences?
SLI is a measured metric, SLO is the target, SLA is the legal promise with penalties.
What is distributed tracing?
End-to-end spans connected by a trace-id showing where time is spent across services.
Blue/green vs canary deploys?
Blue/green flips all traffic between two stacks; canary shifts small traffic to new code gradually.
MTTR and MTBF-define them.
MTTR: average repair time; MTBF: average time between failures, a reliability indicator.
Security & Auth
OAuth2 vs OpenID Connect?
OAuth2 delegates access; OIDC extends OAuth2 with identity (ID tokens and user info).
Access token vs refresh token?
Short-lived access tokens call APIs; refresh tokens mint new access tokens securely.
Secrets management best practice?
Keep secrets out of code; use a vault/KMS, rotation, auditing, and least privilege.
How do you prevent SQL injection?
Parameterized queries SELECT ... WHERE id = ?, input validation, and least-privileged DB users.
Testing & CI/CD
Unit vs integration vs contract tests?
Unit isolates logic; integration hits real components; contract tests lock producer/consumer API shapes.
Mocks vs stubs-difference?
Stubs return fixed data; mocks also assert interactions/expectations.
What is a migration and why version it?
Schema or data changes; versioned migrations make deploys repeatable and reversible.
How do you gate releases in CI?
Run tests, linters, security scans; enforce SLO budgets and canary checks before promotion.
Cloud & Deployment
Containers vs VMs-trade-offs?
Containers share the kernel and start fast; VMs isolate hardware but are heavier.
Horizontal vs vertical scaling?
Horizontal adds instances; vertical adds CPU/RAM to the same instance.
Infrastructure as Code definition.
Declarative cloud state in code (e.g., Terraform) enabling review, drift detection, and repeatability.
L4 vs L7 load balancing?
L4 routes by TCP/UDP; L7 understands HTTP/headers/paths for smarter routing.
