Bucketing Interview Questions

Assign every value to the interval between two adjacent boundaries and report how many landed in each. This Bloomberg question is binary search per value with a precise exclusion rule: anything below the first boundary or at or above the last is dropped rather than clamped. You will pick the search variant that matches the half-open intervals, handle values sitting exactly on a boundary, and keep the per-value cost logarithmic.

In this classic Meta interview question, candidates are given a collection of strings and must partition them into clusters of words formed by rearranging the same letters. The challenge tests string manipulation, hashing techniques, and frequency counting to achieve optimal performance. A common follow-up explores sorting the resulting clusters by population size.
