Angular appears in 18.2% of Stack Overflow survey responses among web frameworks—common in enterprise and regulated teams (Stack Overflow 2025 Technology). Your interview should test maintainability at scale, not whether they can spell “NgModule.”
These five questions align with themes Indeed lists for front-end developers using major frameworks: architecture, debugging, performance, and shipped experience (Indeed: Front-end developer interview questions).
1. “How do you structure feature modules vs shared libraries in a large Angular app?”
Strong candidates explain lazy loading, boundary rules, and how they prevent circular imports. Weak answers describe one giant AppModule.
2. “What triggered unnecessary change detection—and how did you fix it?”
Performance on Angular teams often comes down to change detection strategy and async pipe usage. Listen for profiling, OnPush, and trackBy—not random optimization.
3. “When do you use RxJS operators in a service vs pushing logic into a component?”
RxJS discipline separates senior Angular work from copy-pasted subscribe blocks. Good answers mention unsubscription, error streams, and testability.
4. “Compare reactive forms vs template-driven forms for a complex workflow you built.”
Forms are daily work in enterprise Angular. You want validation strategy, accessibility, and how they handled dynamic fields.
5. “Tell me about upgrading Angular major versions on a live product. What broke?”
Migration stories reveal real experience. Strong candidates mention breaking changes, incremental updates, and test coverage that caught regressions.
