My interview was at 2pm and I arrived at 1:15pm and there was already people in line. Therefore be early instead of on time! This way you get a front seat on the object recognition test. Which is needed when you are looking for detail (this way you can focus fully on the screen). The interview is straight forward. 20 questions for object recognition test. Its either you see a grenade, knife, gun or none; each slide is only one answer. 100 pre qualification questions and you only have 60 minutes to complete it. Basic math, english, patterns etc. Examples: what is 10% from 60? Or which word of the four given is misspelled? Then after you have successfully passed both tests you have a quick 1 on 1. My interviewer was not intimidating and very nice. After the questions they give you a form for which a doctor must fill out. Be yourself and try your best!
