❌ Mistake #1: Passive Learning Mindset (Affects 78% of Interns)
🚫 The Problem
Treating internships like extended classes, waiting for instructions rather than actively seeking growth opportunities.

Communication failures include:
- Status update neglect: Not proactively sharing progress on projects
