Mini-Circuits Mechanical Engineer interview questions

The HR person emailed me two documents full of questions that took at least 1.5 hrs to complete. Then she called to set up an interview date and told me to clear my schedule. The interview would take s AM and left at 4:45PM. They had me take english, math, and logic exams. The HR person graded them and then interview me. Afterwards they sent me over to another building where the Department manager interviewed and made me take an autocad test. There was at least 1 hour of waiting in between each of the above steps.
