Frontend System Design Interviews
Answer design questions about building news feeds, autocomplete, image galleries, and dashboards by discussing component architecture, state, API design, and performance.
What These Interviews Test
Senior frontend interviews ask you to design a non-trivial UI feature end-to-end: news feed, autocomplete, image gallery, infinite scroll dashboard. They evaluate architecture, trade-off awareness, performance instincts, and communication — not framework trivia.
The Standard Structure
Most 45-60 minute interviews follow: 1) Clarify requirements (5 min). 2) Sketch high-level architecture (10 min). 3) Component breakdown (10 min). 4) Data fetching + state (10 min). 5) Performance + accessibility (10 min). 6) Deep-dive on one area (interviewer's choice).
