Here are my numbers for the class of 2011 employment reports. Note that HBS does not release firm-specific numbers, but they supposedly increased consulting placement to 29% for the class of 2012 from 24% for the class of 2011 (see this andthis).

It's impossible to format posts here. I don't know how to make tables like the OP did.

Format is as follows:
<School> <FT MBB Hires> <% of FT seekers hired by MBB> <Intern MBB Hires> <% of intern seekers> <sum of FT+intern> <#FT Job-seekers> <#Internship seekers>
McK #FT % #intern % FT+intern
Bain #FT % #intern % FT+intern
BCG #FT % #intern % FT+intern
