Define and calculate Weekly Active Users

Source: interviewintermediate

WHAT IT TESTS: turning 'active' into a defensible metric. OUTLINE: define a meaningful active action, count distinct users over a rolling 7-day window, and exclude bots and background syncs.

WHAT IT TESTS: whether you can operationalize a vague growth metric rigorously. ANSWER OUTLINE: first define active as a meaningful human action (sending a message, reacting, opening a doc) rather than merely the app being open; then count distinct user ids performing that action within a 7-day window, deciding rolling versus calendar week. Address pitfalls: filter out bots and service accounts, exclude background syncs and automated pings that fire without a human, and de-duplicate users across devices.
