💬 Potential Interview Questions

How would you design a scalable Express/Node service that powers a workflow IDE?
Use a layered architecture (routing → controllers → services → repositories), async I/O, connection pooling, and horizontal scale behind a reverse proxy with rate limiting and circuit breakers. Make all mutations idempotent and queue side effects.
How do you model and execute user-defined workflows safely and reliably?
Represent flows as validated DAGs with schema versioning; enforce type-safe node contracts and static checks before execution. Run with transactional checkpoints, retries with backoff, and exactly-once semantics via an outbox pattern.
What are best practices for error handling in an Express app?
Use centralized error middleware, map operational vs. programmer errors, attach correlation IDs, and return typed problem details. Never leak stack traces in production; log structured JSON with levels.
How do you ensure React UI performance in a complex, canvas-like editor?
Use memoized selectors, React.memo/useCallback, windowing/virtualization, and offload heavy computations to Web Workers. Code-split large panels and debounce frequent updates.
Describe your approach to testing across the stack.
Unit test pure logic (Jest), integration test APIs against a real Postgres in Docker, and E2E test critical flows with Playwright/RTL. Add contract tests for public APIs and snapshot/visual tests for the editor.
How would you design versioned REST APIs for long-lived enterprise integrations?
Adopt URI or header versioning, stable resource shapes, pagination/filtering, and idempotency keys for unsafe methods. Provide deprecation policy, webhooks for async results, and HATEOAS where useful.
What security controls are essential for identity-centric apps?
Use OAuth 2.0/OIDC (PKCE for public clients), short-lived access tokens with refresh flow, and scope-based authorization on the server. Enforce CSP, secure cookies, CSRF protection for same-site forms, and audit trails.
How do you use PostgreSQL effectively from Node.js under high load?
Pool connections (pg pool), keep transactions short, prefer keyset pagination, and create covering/composite indexes based on query patterns. Use ON CONFLICT upserts and appropriate isolation levels to avoid contention.
How would you containerize and deploy this service?
Build minimal multi-stage Docker images, run as non-root, externalize config via env/Secrets, and add liveness/readiness probes. In Kubernetes, set resource requests/limits, HPA, and rolling updates with canaries.
How do you make data-driven UI/feature decisions and monitor production?
Instrument with OpenTelemetry for traces/metrics/logs, capture Core Web Vitals and user events, and set SLOs with alerts. Run guarded experiments (A/B), analyze impact, and ship via feature flags with gradual rollout.
