This was basically the whole interview compressed into one question.
Choose one concrete SaaS project you built with Angular and narrate its evolution from initial MVP to scaled product, focusing on the architectural decisions and patterns that changed as complexity grew. Balance technical depth with business impact, showing how your choices enabled the product to scale without sacrificing developer velocity.
Pro tip: Frame your answer around trade-offs rather than just successes—explain what you tried, what broke, and how you adapted. This demonstrates the adaptability and system design thinking that senior frontend roles at companies like Navan value.
Briefly describe the SaaS product, its scale (users, features, team size), and your role. This anchors the story and shows you can communicate technical context to stakeholders.
Explain the Angular version, core patterns (e.g., smart/dumb components, services, state management), and why you chose them for the MVP. Highlight how you balanced speed of delivery with maintainability.
Detail the specific pain points that emerged as the product grew—e.g., performance bottlenecks, state management complexity, bundle size, or team coordination. This shows you can diagnose architectural issues.
Walk through the architectural changes you made in response, such as adopting NgRx, lazy loading modules, micro-frontends, or optimizing change detection. Emphasize the trade-offs and results.
Summarize the impact on performance, developer experience, and business metrics. Share what you would do differently and how these lessons apply to future scaling challenges.
