How to prepare for Perplexity
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.
Array
Array problems are common and can be tricky. Mastering them ensures you're ready for coding challenges that involve large datasets.
Hash Table
Hash tables are crucial for solving problems involving fast lookups and optimization, so be prepared for frequent usage.
Tree
Tree problems test your understanding of hierarchical data structures, often appearing in system design or algorithmic problems.
