Does McKinsey hire from Big 4?

Transitioning from the Big 4 to MBB Consulting

If you are working in a Big 4 strategy practice, moving to a top-tier firm like McKinsey, Boston Consulting Group (BCG), or Bain—often referred to as MBB—is a very realistic career path. Data shows that roughly 39 percent of experienced professional hires at these elite firms previously worked at another consulting company.

The vast majority of this talent pool doesn't just come from anywhere; they transition directly from the dedicated strategy arms of the Big 4 network. This includes teams such as EY-Parthenon, Monitor Deloitte, PwC's Strategy&, and KPMG's Global Strategy Group (GSG).

Because these internal strategy groups maintain rigorous analytical standards and client-facing expectations similar to MBB, consultants working there build highly transferable skill sets. If you have solid case interview preparation, strong problem-solving frameworks, and proven project delivery experience within a Big 4 strategy team, you are already speaking the language that McKinsey and its peers look for.
