Capital One Product Manager interview questions

I failed in the very initial mini case interview, you will learn something from this one. So the interview starts with Tell me about yourself, Why Capone?, which CapOne product do you like the most? And then he gave me a problem on shopping. Very humble and supportive interviewer. even when I answered, he kept on asking anything else? something more? giving me hint to speak more (but I lost in technical answers& if you know system design it may help you) so its ideally : 1. Product sense or design/ business strategy 2. Core technical Implementation of whatever you have answered in 1 (helpful if you know technical words in your answer) 3. UI & UX, presenting a sample & asking if you can rectify the defects 4. Analytical round (presenting a data of AB testing results) & asking your insights 5. Situational question. All the best :)
