Here's how I recommend working through this course:
Start with Leadership Principles (Section ). This is what makes Amazon unique. Skip it and you'll fail the behavioral portions.
Behavioral Interviews (Section ). Learn STAR format and build your story bank.
Coding Patterns (Sections -). problems covering Amazon's favorite patterns.
System Design (Section ). Required for L5+.
Offer & Negotiation (Section ). Amazon's compensation is unusual. Knowing the structure helps you negotiate.
