Capital One Project Manager interview questions

I got the Cap One Shopping Browser Exten Case. It's not like the traditional produce sense cases where you are improving a feature or product, they just go straight into questions. First question I was asked was, beyond the revenue stream what value does this product bring to Capital One? (Why would capital one build this product) As a PM for Capital One, you want to personalize offers via Capital One Shopping through targeted email offers. Identify which products you would send to customers to increase the number of purchases with a referral link. Then I was shown a draft email and asked how I would improve it. Then I was shown some metrics for before and after changing the personalized marketing emails and asked what my observations were. Those were all the questions. I didn't pass this round.

Graphs, solving for % discount, etc.
