You left out the most important aspect of the full-time program. The internship! That really is a great way to switch careers or even determine if brand management is what you're passionate about. Most people I know who have done MBAs from top schools part-time (Booth, Kellogg, etc.) wish they had gone full time since part-time is so difficult from a work-life balance standpoint and your experience is not as rich as a full time experience. Oh and as far as recruiting goes, typically part-time students aren't recruited alongside the full-time students because technically the part-time students have jobs already!
