How to prepare for Hubspot
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.
