Sample Vetting Questions

Example questions at senior and principal level for Angular, with what a strong answer covers. They show the depth TeamStation AI tests. They are not a real candidate interview.

Change detection and speed

  1. Principal level, Mental Model. A dashboard with 200 widgets stutters on every websocket message. How do you find the cause and what do you change first?

    A strong answer covers: Profiler to see which components check on each message; The default change detection strategy and what triggers it; Moving to on push style components and immutable inputs; Signals or streams that update only what changed.

  2. Staff level, Accuracy. What does zone.js do for an Angular app, and what goes wrong when third party code runs inside it?

    A strong answer covers: Patching async APIs to trigger checks; Needless checks from timers and events; Running noisy code outside the zone; The move toward zone free change detection.

  3. Principal level, Procedural Knowledge. An Angular app has a 4 MB initial bundle. What is your order of attack?

    A strong answer covers: Bundle analysis before changes; Lazy loaded routes and deferrable views; Duplicate and heavy libraries; Measuring real load, not only bundle size.

  4. Staff level, Cognitive Load. A list renders 10,000 rows and the browser freezes. What are your options and their costs?

    A strong answer covers: Virtual scrolling; Pagination or server side filtering; Track by identity so rows are reused; Accessibility with virtualized lists.

State, streams and data

  1. Principal level, Mental Model. A component subscribes to three streams and sometimes shows stale data. How do you reason about it and fix the class of bug?

    A strong answer covers: Higher order stream operators and what each cancels; Race conditions between requests; Unsubscribe and lifecycle; Deriving state instead of storing it.

  2. Staff level, Accuracy. When do you choose signals, plain streams or a store library, and what is the cost of getting it wrong?

    A strong answer covers: Size and shape of the state; Learning and debugging cost; Testing; Not mixing three styles without a rule.

  3. Principal level, Cognitive Load. Design offline friendly editing of a record with optimistic updates and conflict handling.

    A strong answer covers: Local queue of changes; Version or etag per record; Rollback and conflict screen; Safe retries.

  4. Staff level, Procedural Knowledge. A memory leak appears after users navigate between screens for an hour. How do you find it?

    A strong answer covers: Heap snapshot comparison; Subscriptions and listeners not removed; Detached DOM nodes; Services holding references.

Architecture and scale

  1. Principal level, Mental Model. How do you organize a 500 component Angular codebase so six teams can work without collisions?

    A strong answer covers: Feature areas with a small public surface; Standalone components and clear imports; Enforced dependency rules; Shared library ownership.

  2. Staff level, Accuracy. Compare modules based and standalone component organization, and describe a safe migration.

    A strong answer covers: What changes and what does not; Automated migration steps; Order: leaf first; Tests as the safety net.

  3. Principal level, Clarity. Your design system is forked by three teams. What do you change?

    A strong answer covers: A faster contribution path than forking; Versioning and stable APIs; Tokens and accessibility built in; One accountable owner.

  4. Staff level, Cognitive Load. Plan an upgrade across five major Angular versions for a large app with a deadline.

    A strong answer covers: One version at a time; Automated update tooling; Third party library compatibility; Release and rollback plan.

Testing and accessibility

  1. Staff level, Mental Model. What do you cover with component tests, what with end to end tests in an Angular app, and what do you stop testing?

    A strong answer covers: Behavior a user can see; Contracts with the server; Flaky test cost; Duplicated tests.

  2. Principal level, Accuracy. Tests pass and a screen reader user cannot complete a form. What does that show and how do you close the gap?

    A strong answer covers: Roles, names and labels; Focus handling and error announcements; Automated plus manual checks; Keyboard paths.

  3. Staff level, Procedural Knowledge. An end to end test fails 1 in 20 runs. How do you find the cause?

    A strong answer covers: Repeated runs to reproduce; Waiting on state, not time; Deterministic data and isolation; Network and animation timing.

  4. Principal level, Cognitive Load. Design a release process for an Angular app used by 200,000 people with weekly releases.

    A strong answer covers: Feature flags; Staged rollout and metrics; Fast rollback; Cache and version skew between app and API.

Production and debugging

  1. Principal level, Cognitive Load. Errors appear for 0.5 percent of users on one browser version. How do you find the cause?

    A strong answer covers: Release and browser tags in error tracking; Source maps; Feature detection and polyfills; A flag to switch the change off.

  2. Staff level, Accuracy. Server side rendering is added to an Angular app. What breaks, and how do you find it?

    A strong answer covers: Browser only APIs on the server; Hydration mismatches; Cache and per request state; Measuring the gain.

  3. Principal level, Procedural Knowledge. Users report that the app keeps showing an old version after a release. How do you diagnose and fix it?

    A strong answer covers: Caching headers and the service worker; Version skew between app and API; A forced refresh strategy; Monitoring adoption of the new version.

  4. Staff level, Clarity. Explain to a product manager why a small change touched 30 files.

    A strong answer covers: One cause in plain words; Options with cost; What prevents it next time; No jargon.

Leadership and AI tools

  1. Principal level, Accuracy. An AI assistant generated a 500 line component. What do you check first?

    A strong answer covers: Behavior against the requirement; Change detection and subscriptions; Accessibility; Tests and bundle cost.

  2. Staff level, Clarity. Build or buy a data grid. Who is in the room and what evidence do you bring?

    A strong answer covers: Total cost over two years; Accessibility and performance; License and exit path; What the product needs.

  3. Principal level, Cognitive Load. Leadership wants to leave Angular to hire faster. How do you respond?

    A strong answer covers: The actual hiring problem; Cost and risk of two stacks; A bounded pilot; A decision record.

  4. Staff level, Procedural Knowledge. How do you mentor a mid level engineer whose Angular components work but are hard to test?

    A strong answer covers: Examples from their code; Structure and naming habits; Pairing then review; Visible progress.

The five Axiom Cortex axes, with one example each

  • Procedural Knowledge. Walk me through finding why one screen re-renders on every keystroke. Looks for: Order of steps; What each step proves; What you do if the profiler shows nothing.
  • Mental Model. Why does an unsubscribed stream keep a component alive after the user leaves the screen? Looks for: References held by the subscription; Lifecycle of the component; The right fix, not a workaround.
  • Accuracy. What does on push change detection guarantee, and what does it not? Looks for: Correct limits; When it skips a check; Says when it is unsure.
  • Clarity. Explain to a designer why the screen flashes old data before new data appears. Looks for: One cause named; One decision for the listener; Plain words.
  • Cognitive Load. A release just went out, errors are up, a customer is escalating and two dashboards disagree. What do you do first, second and third? Looks for: A clear order; Facts kept apart from guesses; Stays correct as facts change.
