I applied in-person. I interviewed at PIX System in May 2015
Interview
It was pretty extensive and met with many people in the company. Casual but thorough. Lot of questions. Nothing too tough, but they do explore what you have to offer pretty thoroughly. All in all it was a good experience.
Interview questions [1]
Question 1
They asked me to teach them how to do something. And asked a lot of questions. Pretty laid back and casual. They ask all the normal stuff but do ask some technical questions to see how much you know in case they can use it in some way.
