How to prepare for Xai
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.
Tree
Xai’s interviews often focus on tree problems that assess recursive thinking and data structure manipulation skills.
Binary Tree
Binary tree traversal and manipulation are core to many of Xai's problem-solving questions, requiring precise algorithm design.
Depth-First Search
Depth-First Search is crucial for many of Xai’s recursion-based questions, especially for tree traversal.
