I applied for these programs (the buying, planning, etc) back in about Sept/Oct I believe. I never heard anything back until about December I believe when I got emails that said they had already completed hiring for these positions and didn't have any left at the moment. Pretty much they are done with hiring which would explain the problems people have been having when it comes to trying to maneuver around the website. They should make that clear, but they don't.
I also talked to a recruiter for these programs at the USC career fair and she said they get most of their candidates directly from people who already work at Macy's and Bloomingdales and who are currently doing internships with them. It pretty much sounded like they only have very few spots left often to "the public" each hiring season. When I was talking to her they had already filled up most of the programs strictly with current interns.
Hope that helps.
