DSA Masterclass Module 2: The Problem Solving Mindset

Introduction to the DSA Mindset

The biggest mistake candidates make is jumping straight into coding. In a FAANG interview, coding is only 20% of the evaluation. The other 80% is how you think, how you communicate, and how you validate your assumptions.

1. The 5-Step Execution Framework

1. Clarify: Ask about constraints and edge cases.
2. Brainstorm: State the brute force, then optimize aloud.
3. Blueprint: Write pseudo-code or a high-level plan.
4. Code: Implement surgically with clean naming.
5. Validate: Manually dry run with a small example.

Final Takeaway

Treat the interview as a meeting with a coworker, not an exam with a proctor. Focus on the thought first, implemented code second.
