Tell me the courses you have taken in college and if you are familiar with the courses we need to develop.

There was not much of a formal interview. They mostly cared about your success in answering the initial testing questions. Provided you do well on these, there is a great chance you'll get a job offer. They may inquire if you have any background in programming or writing in code. This is a big plus, though certainly not required, so if you do have any coding skills be sure to mention them.
