rushikesh003,
Here's what the Adcom has to say:
"All applications to the Purdue MBA are reviewed by the graduate admissions team and an admissions decision is reached based on a student's undergraduate performance, work experience, test scores, recommendation letters and interview performance. Admission to the MBA program is not in any way related to the capacity of the undergraduate program at Krannert".
From what I think, the backlogs should not matter if you have a good work experience, test scores, recos and stellar interview performance. Hope it helps.
Regards,
Vikram
