General Preparation Advice
- Coding & Algorithms: Ensure your foundation in data structures (Arrays, Strings, Hash Maps, Trees, Graphs) is solid. Practice writing solutions out loud so your reasoning is visible while you code.
- Behavioral: Prepare short STAR stories that show ownership, collaboration, debugging, conflict resolution, learning, and measurable impact. Keep the examples specific and tied to real decisions you made.
