Angular engineering mastery assessment

Readiness means independent evidence across build, explain, debug, and defend. Record examples and dates; do not award mastery from self-confidence or one successful definition.

Build without a recipe

  • compose and lazy-load a standalone feature;
  • design typed component contracts and stable collection identity;
  • separate source and computed signal state;
  • place providers at intentional lifetimes;
  • create deep-linkable routes and unknown/loading behavior;
  • build an accessible strictly typed form;
  • validate/map untrusted HTTP data and model complete async state;
  • encode cancellation/concurrency with the correct temporal policy;
  • write domain, component, route, and HTTP tests.

Explain from a mental model

  • compilation dependency versus runtime provider;
  • view creation, identity, scheduling, and destruction;
  • signal, computed, effect, observable, and ownership boundary;
  • injector hierarchy and lifetime;
  • route navigation policy versus backend authorization;
  • compile-time typing versus runtime trust;
  • CSR, SSR, SSG, and hydration tradeoffs;
  • risk-based verification and performance evidence.

Diagnose methodically

For each item, reproduce, hypothesize, gather discriminating evidence, identify root cause, fix, and add regression protection:

  • stale response or terminated interaction stream;
  • duplicate provider instance or HTTP request;
  • incorrect list identity or stale signal mutation;
  • subscription/resource leak;
  • missing disabled form value or invalid command;
  • flaky timer/singleton/request test;
  • browser global or unstable output during server rendering;
  • measured rendering/startup/network bottleneck.

Defend engineering decisions

  • identify context, constraint, owner, lifetime, trust, and failure boundary;
  • compare at least one viable alternative;
  • include accessibility, security, observability, cost, migration, deployment, and rollback proportionally to risk;
  • name evidence that supports and could reverse the recommendation;
  • change the design when constraints change;
  • distinguish known fact, measured evidence, inference, and uncertainty.

Demonstrate mastery

For every claimed concept:

  • explain it in your own words;
  • apply it without a recipe;
  • survive an analysis/debugging variant;
  • pass a later spaced-retrieval check;
  • record evidence and remaining misconception in the learning map.

Final assessment

Complete the capstone, one unseen debugging drill, and one changed system-design scenario. Have a reviewer cite observable evidence under the capstone rubric. Revisit only the highest-leverage gap, then repeat with a different constraint.

Optional interview readiness can be pressure-tested with the mock interview; it is supporting evidence, not a substitute for applied work.
