MediumSQL · PostgreSQL

Problem

Write a query to identify top-performing content creators based on specific engagement metrics over a rolling 30-day window at TikTok.

Output

  1. One row per included creator with creator_id, creator_name, total_views, total_engagements, engagement_rate_pct, and creator_rank.
  2. total_engagements is likes plus comments plus shares, and engagement_rate_pct is total engagements divided by total views, multiplied by 100 and rounded to two decimals.
  3. Return the top three creators, ordered by rank ascending.
