Columbia IEOR dept obviously can do a much better job when it comes to providing relevant information. It's clear that placement info is the most crucial piece of data that every applicant wants to know.
Until they can account for every single one of their graduate's whereabouts, there will always be lot of rumor about bad placement, specially in a large program like Columbia MFE.
I'm sure applicants will continue to ask the program to provide a more detailed, accurate report of their internship and full-time job. Saying X% received job offer is not enough when competing programs provide a much more comprehensive placement stats. Brand-name may attract more applicants but does not always translate into 100% placement in desired jobs which is the ultimate goal for many people obtaining this degree.
