Merge Intervals is a medium coding interview question covering arrays, sorting — the kind asked at FAANG (Facebook/Meta, Apple, Amazon, Netflix, Google) and AI-first companies like Anthropic, OpenAI, and Nvidia.
Given a list of intervals, merge all overlapping intervals and return the non-overlapping result. Example: [[1,3],[2,6],[8,10],[15,18]] -> [[1,6],[8,10],[15,18]].
