Amazon's SDE II / SDE III / Principal loops emphasize Trees, Graphs, Sliding Window, and DP — with a strong Leadership Principles component that requires you to weave "customer obsession" or "ownership" narratives into your solution walkthrough.

What Amazon looks for by level

Level	Focus
SDE I	Arrays, strings, hashing, trees, easy DP
SDE II	Medium graph, sliding window, backtracking, medium DP
SDE III / Principal	Hard graphs, hard DP, system design + algorithm blend

What Amazon interviewers care about

• Leadership Principle stories. Every solution should map to a principle: "This code shows Customer Obsession because…"
• Practical over academic. Amazon prefers "readable + shippable" over "clever + optimal."
• Handle production concerns. What if input is empty? What if two things fail concurrently?
• Bar Raiser round. One interviewer will be from a different org — expect a hard behavioral + algorithmic mix.
