Find leading indicators of long-term churn

Source: interviewintermediate

WHAT IT TESTS: turning a lagging metric into early signals. OUTLINE: cohort renewers vs churners, compare first-30-day engagement depth and breadth, validate correlations and check causality. RED FLAG: jumping to a model before defining the cohort and target.

WHAT IT TESTS: whether you can reverse-engineer a lagging metric into early, actionable signals. ANSWER OUTLINE: define renewed vs churned cohorts with enough tenure, extract first-30-day features (logins, breadth of features used, time-to-first-value, key action counts), compare distributions between groups, and test which gaps are statistically meaningful and plausibly causal. RED FLAG: building a churn model immediately, leaking post-30-day data into features, or confusing correlation with cause without a holdout or experiment to confirm.
