Capital One Software Developer interview questions

(Skype interview) A recruiter contacted me and had me complete a coding assignment a few days prior to the interview. This code was used as a the basis for the technical half of the interview. They ask you to go over your approach to solving the problem, any assumptions you made, how you tested it, etc... After explaining the code line by line my interviewer asked me how it would operate under a different data structure and with alternative inputs. It was all fairly straightforward. The second half of the interview consisted of a job fit in which they just want to learn more about you and your motives.
