System Design Interview Pacer

A non-intrusive 4-phase timer for system design interviews.

Master your System Design Interview timing with this non-intrusive, automated pacer. Why use this? The biggest challenge in 45-minute system design interviews is time management. Candidates often spend too long on requirements or rush the deep dive. This extension solves that by breaking the 45 minutes into the standard 4-phase structure recommended by top engineering leaders. Features: 4-Phase Structure: 1. Requirements & Scope (5 min): Define functional/non-functional requirements. 2. High-Level Design (10 min): Diagram core components and API. 3. Deep Dive (25 min): Scale, bottlenecks, trade-offs (longest section). 4. Wrap-up (5 min): Summary and Q&A. Smart Transitions: Automatically moves to the next phase when time runs out. Non-Intrusive Overlay: A semi-transparent glassmorphism widget that floats over your drawing board (Excalidraw, Miro, Lucidchart). Visual Alerts: Gentle yellow glow at 2 minutes remaining, red pulse when time is up. Draggable: Move it anywhere on screen to keep your workspace clear. Privacy: 100% Client-side. No data is collected or sent to any server. Storage" permission is used only to save your timer state if you refresh the page.
