About this puzzle

Max Meetings — practice the decision, scored against the optimum

What does the Max Meetings puzzle teach?

Fit the most non-overlapping meetings into one room — sort by end time, take the next that starts on/after the last end. Picking by earliest start blocks more than it fits.

Why do interviews ask about this?

Activity selection is the canonical greedy proof — interviewers want you to justify sorting by end time over the tempting earliest-start or shortest-meeting heuristics.

How is it scored?

The engine computes the provably-optimal answer for the exact instance you played (dynamic programming, shortest-path, or exhaustive search — never a heuristic) and scores your attempt as a percentage of it. No login needed to see your score.
