System Design FAQs
How does GhostDesk assist during System Design interviews?
GhostDesk listens to the interviewer's prompt via real-time audio transcription or OCR of shared design boards (Excalidraw, Miro, Google Docs). It instantly delivers structured High-Level Design (HLD) outlines, database choices (SQL vs NoSQL), caching strategies (Redis, Memcached), message brokers (Kafka, RabbitMQ), and estimation calculations.
Does it help with Low-Level Design (LLD) and Object-Oriented Design?
Yes. GhostDesk provides class diagrams, design patterns (Factory, Strategy, Observer, Singleton), and clean code implementations in Python, Java, or C++ with SOLID principles.
Is GhostDesk invisible while I draw on Excalidraw or Miro?
Yes. With hardware-level OS capture exclusion, you can share your entire desktop or browser window running Excalidraw. The interviewer only sees your drawing board while GhostDesk floats seamlessly above your screen.
What systems can GhostDesk design?
Everything from TinyURL, Instagram Feed, Uber Geohashing, WhatsApp Chat, Distributed Rate Limiter, Payment Gateway, to Video Streaming platforms (Netflix/YouTube).
