Interview had 3 stages. First with a computer CAD test on a commputer. Fairly simple, needed to know how to manipulate and scale with xrefs. Second stage is HR, who asked you standard situational interview questions like "your biggest problem and how you solved it", etc. HR will then test you technically. Bring your tools and be ready. 3rd stage is manager, who will grill you. One of the toughest interviews I have been through.
