Amazon SDE off-campus — LRU cache, trees and an SDM round

## Online assessment
Several distinct parts: three coding problems (two medium, one hard) across **dynamic programming**, strings and graphs; a work-style section with situational logic and data-interpretation questions; a debugging exercise working through logs to find the underlying issue; and a slider-based psychometric behavioural section.

## Round-by-round

### Round 1 — DSA
An **LRU cache** design problem (medium) plus a **binary search** question.

### Round 2 — DSA
A step up: a hard binary tree problem paired with a **graph BFS** question, with time and space complexity expected for both.

### Round 3 — Behavioural (with an SDM)
Entirely focused on the **Leadership Principles**. I'd prepared seven or eight personal stories covering challenges, handling feedback and taking ownership — having them ready made a real difference.

## Verdict
Offer within 5–6 days of the final round. **Selected.**
