Compute seller counts and vehicle share

You are given two tables:

1. listing_interactions
   • buyer_id BIGINT
   • seller_id BIGINT
   • event_date DATE
   • product_id BIGINT
   • listing_interactions INT — number of buyer-seller interactions for that product on that date
2. dim_all_products
   • product_id BIGINT
   • category STRING
   • snapshot_date DATE
   • create_date DATE
   • country STRING

Assumptions:

• Join the tables on product_id .
• All dates are stored in UTC.
• Unless otherwise specified, use all available data.
• For Question 1, define a product as having multiple interactions if the total listing_interactions summed across all rows for the same (seller_id, product_id) is greater than 1.
• For Question 2, define newly created listings in the US as products with country = 'US' and create_date in the last 7 calendar days, inclusive of CURRENT_DATE .
• For Question 2, the numerator and denominator should both use SUM(listing_interactions) .

Write SQL for the following two tasks:

1. How many sellers have more than 3 distinct products that each have multiple interactions?
   • Return one row with column: seller_count
2. Among newly created US listings from the last 7 days, what percentage of total listing interactions comes from the vehicle category?
   • Return one row with column: vehicle_interaction_pct
   • Express the result as a percentage from 0 to 100.
