I applied online. The process took 3 weeks. I interviewed at Capital One in Mar 2015
Interview
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.
