Went through a staffing agency and got sent straight to the in-person interview. Interviewed with three people, one at a time at their Exton, PA office for half an hour each. The atmosphere was very relaxed, and the people were friendly. There was not much in the way of technical questions, aside from the one mentioned below. There was also an online personality, professionalism, and logic exam. This took roughly 40 minutes to complete. The logic questions were simple; you are given a few statements and then were told to select the only answer that can be true. Although the exam is multiple choice, it is highly recommended to have a stack of paper to write on.
