BusinessWeek - Ritu Khanna wasn't the luckiest of business school applicants. When she first applied , she was waitlisted at New York University's Stern School of Business (Stern Full-Time MBA Profile), and rejected by three others. London Business School (LBS Full-Time MBA Profile) and Columbia Business School (Columbia Full-Time Profile), and the Stanford Graduate School of Business (Stanford Full-Time MBA Profile) all gave her the cold shoulder.
