Overview: This question evaluates a candidate's ability to design a stateful, multi-part class that combines interval tracking with incremental balance accounting, a common pattern in coding interviews for backend systems roles. It tests practical application skills across data structure design, running-total bookkeeping, and computing maximum overlap within a time window, moving from straightforward bookkeeping to a harder interval-scheduling extension.
