How to prepare for Cloudflare
The prep layer should stay practical: what to review, which LeetCode patterns recur, and how GhostInterview fits the live round instead of just prep week.
Prep focus
Use GhostInterview during the actual interview
GhostInterview is not just for prep. Use it during live interview loops and follow-up pressure while the conversation is still happening. On supported platforms, the overlay is designed to stay hidden on screen share.
Related LeetCode patterns
These are the recurring problem families worth reviewing before a similar loop.
Design
System design is critical at Cloudflare. You’ll be assessed on your ability to create scalable and efficient systems under constraints.
Hash Table
Hash tables are a common theme in coding interviews. Cloudflare looks for solutions that make efficient use of data structures.
Graph
Graph problems are frequently tested to assess algorithmic thinking and optimization skills. Understanding graph theory is crucial for Cloudflare’s technical rounds.
