Capital One Statistician interview questions

First round was an easy phone interview, then three on site interviews. They invited me over after the phone interview. Two fo three on-site interviews were technical and one was personality test.

the interviewer started by talking about the internship, the responsibilities and duties, and possible promotions. then he started the techniques questions part. he asked about 5 big questions, all relevant to statistics. I would say at least mediate level of statistics. The easiest questions is to interpret a 95% confidence interval; while the hardest one is asking how to deal with a very large data, like what is your thought process and what techniques you might want to use. I did not get a feedback on my answers so i did not know whether my answer is correct or not.
