Most-asked Microsoft Data Engineer questions
Ranked by how often each question appeared in reports for this exact position. Answers are written by our team.
Given meetings with start and end times, identify all overlapping pairs.
Sort meetings by start time. For each meeting, compare against all previous ones to detect overlaps (two meetings overlap if meeting₁.start < meeting₂.end AND meeting₂.start < meeting₁.end; with sorting, just check if current.start < previous.end). Collect all overlapping pairs. Optimize with an interval tree or sweep line for O(n log n + k) complexity. The key insight: sorting reduces pairwise checks to linear scans through candidates that could actually overlap.
