Microsoft·Software Engineer·Onsite - Coding / Algorithms
Jul 2026
Microsoft SWE interview with a classic interval merging problem. Pretty standard algorithmic round, nothing too surprising, but the follow-up discussion on complexity kept it from being totally routine.
- Given an array of intervals, merge all overlapping ones and return the resulting non-overlapping set. Walk through an efficient approach and its time complexity.
“Sort by start time, then walk through and merge greedily.” The rest of the author's notes on Software Engineer interview at Microsoft, Onsite - Coding / Algorithms round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
