starts with a brief questionnaire (~30 questions), another one that's around 100 questions, then an in person test (extremely easy, obviously used as a tool to weed out those with an exceptionally low IQ). After these tests the real interviews start. First one is with 2 to 3 mid level managers in the department. If you pass that you move on to the final interview with the plant manager, the department head, and an HR representative. Should you pass that, you are hired.
