Capital One Business Analyst, Associate interview questions

Had a online assessment to complete. Answering questions based on an excel data sheet. Then final round interview: 2 case interviews about credit cards and one product interview where they ask you to describe a tech product you like, how you would improve it or 10 ways to improve an umbrella. I definitely recommend practicing complicated math questions and basically ignore developing a framework. They want to see how you can quantitatively think, not really conceptually. Case questions: what is the break even point for a bank to switch from in-person check deposits to online deposits? How would you measure the effectiveness of an online promotion on customer revenues?

Recruiter mixed up interview link for first phase of interview process. They did not follow up, and should do so of their own volition. This was not a great experience on work day where I also had appointments.
