One interview with department manager and got a call 5 days later with an offer. Interview really depends on the manager, mine was formal and exam-like whereas others I've had with Nordstrom have been laid-back and conversational. Prepare to answer mostly standard behavioral questions and questions about your previous experience and how it relates to sales.
So easy, I went to a job fair and was hired on the spot. They need people in the kids department, that's the easiest section to get into. They just ask about your personality and who you are.
Was inside Barton creek mall, hiring manager was prompt and clear with questions ranging from how I would handle difficult customers, to my personal experiences that could apply to the job.
