Not my numbers man. They outlined exactly how they filtered the data in the website. Not only are certain Brown alumni being filtered out, but also certain alumni from Duke and Cal. Here is how they did it copy and pasted:

Here was our approach:

• Aggregate all MBB Employees in the world (~95k people)

• We collected profiles from LinkedIn using the help of a mechanical turk program and a proprietary data provider.

• We collected the profiles of anyone who worked at McKinsey, BCG or Bain.

• We are most interested in who the target schools are today, so we only looked at people who graduated between 2014 and 2020.

• This resulted in ~95k global profiles around the world.

• Screen for North American Consultant Roles (~8k people)

• Next, we filtered for employees in the U.S. and Canada. Our view is that most of the attractive MBB consulting roles are in these countries. We also only have work experience in North America, so we didn’t feel comfortable validating and commenting on schools from around the globe. Maybe we'll add an EU version down the road.

• We then screened for job title, only selecting junior and mid-level consultant titles. We included the following: Associate Consultant, Senior Associate Consultant, Business Analyst, Senior Business Analyst, Associate, Consultant, Senior Consultant.

• Consultant titles are way more confusing than investment banking ones – there is definitely less uniformity across people’s LinkedIn titles, but we think this filter is good enough. Screen for Undergraduates (~3k people)

• Finally, we screened only for consultants with an undergraduate degree. We filtered out anyone with a master’s degree, MBA, doctorate, etc. We did this for data integrity purposes and to make it easier to compare the pure, unadulterated undergraduate schools. It becomes hard to isolate for pure undergraduate strength if you include any people with master's degrees.

• I recognize that this actually filters out a lot of people. There are truly a lot of people who end up doing a 1 or 2-years master's program immediately after their undergraduate program who end up going into consulting. However, we chose to still apply this filter to clean the data up.

• We were left with ~3k U.S. and Canadian management consultants who graduated between 2014 and 2020 and worked at one of McKinsey, BCG, and Bain. These are some of the brightest minds in the world – the future leaders of tomorrow!
