Capital One Technology Development Program interview questions

Three interviews back to back. One was a behavioral interview, which consisted of basic questions like work you've done, your biggest weakness, etc. One was a job fit interview which consisted of creating 2 algorithms. One was a case study - I was told this would be a business problem which required basic math, but this was far from the truth. First was given code pertaining to encryption and had to explain it. Then had to write code for an application that could use the encryption code to encrypt all the files in a directory.
