I took a total of 3 interviews, first one was via phone, second in person at local office and finally a 3rd in person interview preempted by a 350 question assessment. The assessment had some higher end high school math question with geometry and algebra. The middle 300 questions were repetitive and easy enough but answer consistently, and the final part had 5 to 7 open ended timed scenario written responses. The whole thing took me about 90 min .
