RH Design Sales interview questions

I was e-mailed out of the blue and asked if I was interested in interviewing for a Design/Sales job. The first interview consisted of speaking with the Lead Designer and also the Store Manager and lasted over 2 hrs. The 2nd interview was 4 or 5 days later with the Assistant to the Store Manager. This 2nd interview lasted about 1.5 hrs and she indicated that if I continued the interviewing process I would participate in at least one more phone interview, maybe more, and it would continue to be a long interviewing process; possibly another couple of weeks. It seemed a rather grueling/draining experience as I was recruited out of the blue and did not exactly know what the specifics of the position were, nor the exact skill set they were seeking. I always felt on the defensive and like I could not gear-up ahead of time with prepared questions, list of strengths, etc.
