Amazon Frontend Engineer Interview Questions

I would use semantic elements, preserve keyboard navigation, and make focus movement predictable across modals, filters, and checkout flows. Accessibility matters especially in commerce because users must be able to complete critical actions reliably.

I would serve the right image size for the device, lazy load offscreen content, and reserve space to avoid layout shift. If needed, I would also use progressive loading or responsive formats so the experience feels fast without looking degraded.

I would focus on the critical paths, including success, failure, retry, and edge-case states. These flows need reliable integration coverage because even a small UI regression can have direct business impact.

I would make the relevance obvious, avoid over-notifying, and allow the user to control frequency where appropriate. The key is to keep the surface helpful and timely without making it feel like clutter.

I would define clear module boundaries, shared design primitives, and rules for ownership so teams can move independently. Good architecture here is less about clever patterns and more about preventing integration chaos over time.
