Capital One Principal Data Analyst interview questions

Interviewed with basic Quant ..then moved to hackerrank..had a question on sql and programming. then was given data challenge..for data challenge you are given a dataset and have to come with innovative solutions. I took it lightly .. i feel they were looking for some kind of modelling.. anyways, it is a nice experience and also the HR was really prompt.

Initial phone screen was with all around questions including analytic and technical. Analytic questions were little vague and pertained to their business scenarios. Do no think the interview pattern gave a fair chance to folks who are skilled but not upto the point in expressing. Looked like he was expecting a predefined set of answers for vague and open ended questions.
