I applied through an employee referral. I interviewed at voxeljet (Canton, MI) in May 2016
Interview
Very quick and easy. You just submit your resume, then if they like you they set up an interview. They frequently hire on the spot. There is only an application if you get the job. There is lots of paperwork to fill out upon employment as well.
Interview questions [1]
Question 1
What is your experience with additive manufacturing and 3D printing?
