Seniority-specific Questions for a Angular Developer

Not all Angular Developers bring the same level of experience to the table, and your interview strategy should reflect that. A junior candidate might be eager to learn the basics, while a senior or manager-level candidate should demonstrate leadership, decision-making, and strategic thinking. Recognizing these differences ensures you’re asking the right questions to evaluate each candidate fairly. To make this easier, we’ve outlined interview question sets tailored to different levels of seniority. Use these as a guide to adapt your conversations depending on whether you’re interviewing an entry-level hire or a seasoned professional ready to lead a team.

Questions for a Junior Angular Developer

  • You build a list view that fetches JSON with HttpClient and displays it in a template, how would you structure the service and component, handle loading and errors with RxJS, and render using the async pipe without manual subscriptions?
  • You need a reactive form with a cross field validator for password and confirm password, how would you implement the validator, surface validation messages in the template, and prevent submission until the form is valid and touched?
  • What is the difference between the constructor and ngOnInit, when would you use ngOnDestroy, and how would you avoid memory leaks by relying on the async pipe or takeUntilDestroyed rather than manual unsubscribe?

Questions for a Semi-senior Angular Developer

  • You are asked to lazy load a feature using standalone APIs, how would you define routes with canActivate guards and a preload strategy, and how would you split the code so first paint stays fast?
  • For client state you can choose signals or a store like NgRx, how would you decide between them for a medium product, and how would you model a feature store with derived state and an effect for server calls?
  • A large table scrolls poorly and change detection is hot, how would you profile with Angular DevTools and improve performance using ChangeDetectionStrategy OnPush, trackBy, pure pipes, and CDK virtual scroll?

Questions for a Senior Angular Developer

  • Design a secure auth flow for an API that uses expiring tokens, how would you implement an Http interceptor for attach and refresh with retry and backoff, coordinate guards versus resolvers, and avoid duplicate refresh storms?
  • The app must support server side rendering and hydration, how would you set up Angular Universal, measure Core Web Vitals, and combine @defer and prefetching to improve time to interactive while keeping correctness?
  • You are evaluating micro frontends, how would you use Module Federation for shared libraries and routing integration, handle version skew and shared dependencies, and plan deployment and rollback to avoid user impact?

Questions for a Manager Angular Developer

  • How would you define the architecture and coding standards including ESLint rules, formatting, type safety, shared libraries, API contracts, and architectural decision records with review checkpoints?
  • What end to end release process would you run including CI and CD with unit tests and component tests, end to end tests with Playwright, feature flags and canary rollout, monitoring for errors and performance budgets, and rollback criteria?
  • How would you plan a migration from an older Angular version to the latest including adoption of standalone components, the new control flow with at if and at for, signals for state, the modern build pipeline, and a training and risk plan?
