    Holy cow. If you assign this to me as a task I can probably finish it in a day with some googling, trial and error, etc But doing this right away during an interview? I would have freaked out completely. This guy just nailed it, and the tips are super helpful. Thanks for sharing!

    Shouldn't the average_purchase_value consider only those sessions where a purchase was made? (rows with purchase_value > 0). The conversion rate of each marketing_channel is creating a bias in this metric.

    Why is the data in two separate tables ? It looks like a one to one relationship to me.
