Please look at the employment reports of various schools and see what % of students the school places in marketing roles. Also, what kind of industry are you looking at? Is it CPG, tech, or industry?
Most employment reports will break down the job offers for both industry and functional area. As for schools which provide good opportunities in marketing, Kellogg is definitely on or near the top of the list. But a lot of other schools in the top 15 will provide a good platform too. Duke has a very good program for those who want to pursue marketing. As does Ross since it is a good program with good opportunities in almost all functional areas. I have heard good things about marketing at Indiana (Kelley School of Business) too.
