That Harvard Business School article further reinforces that private sector and public sector all get their human capital and source their talent from a few schools which improves the networking opportunity for those who attended those institutions.
I read through the report earlier this week and a few things popped out.
1. A good 1/3 - 1/2 of HBS' class comes from Ivy's, top private schools and top public schools. This isn't really a surprise to be honest.
2. Like 1/3 of their class worked at either MBB or top IB prior to B-School.
To point 2, consulting and IB is definitely a feeder into top Bschools, but it can also make it tough for you to stand out from your peers who are gunning for the same schools and usually within the same time line as well. Good friend of mine went to Howard U and did MechE and graduated with a solid GPA. He's doing consulting with the best firm outside MBB but the bar to into HBS from his firm is super high. Just in his office alone there are at least 5-6 very well qualified applicants essentially competing for those same spots. He might have been better served by going industry prior to Bschool.
As I think about Bschool in the next 2 years, I wonder if it makes more sense to make an upward and lateral move to a competitor within my industry and then apply to Bschool instead of jumping into consulting or banking and get pooled in with other applicants. So say I worked at Marriott Corporate within Travel and Hospitality, I'd pivot to an Expedia to work within their distribution channel division and my background would be that of Travel & Hospitality going into Bschool.
I'm looking at M7 + Y-SOM
Just a thought
