How would you answer an interview scenario involving pagination and filtering?
In an interview, I would first define pagination and filtering and the problem it solves, then explain how I would set maximum page sizes, validate allowed filters, apply deterministic ordering, push filtering to the data store, and prefer keyset or cursor pagination when offset pagination becomes expensive. I would also call out the main failure mode: unbounded collection endpoints or pagination without a stable unique sort order can cause timeouts, duplicate rows, and missing rows between requests. Finally, I would describe how I would test, monitor, and safely roll back or recover the solution.
