The design position is extremely important to the company. Expect the interview to last the full day (mine was from 9 am to 5 pm). You go through a 'getting to know you' interview, tour the factory, meet managers, and get to 'shadow' your manager, and 2 other interviews (one with HR and the other with the CEO). Then they test your CAD skills with Adobe Illustrator. They just expect you to sketch some sweaters and show off your technique and creative ability.
