Performance reviews at MBB

Hi there,

That’s a great and very insightful question. At top-tier consulting firms, performance expectations are high, but the environment is also built to support rapid development and growth. That said, there are common patterns of underperformance that, if unaddressed, can lead to someone choosing—or being encouraged—to exit.

Here are some examples of issues that tend to raise concerns:

1. Consistently Weak Problem Solving or Analytical Skills
   If a consultant struggles to structure problems, interpret data, or draw out clear insights—even after coaching—that can become a sticking point. These skills are core to the role, and there’s limited tolerance for stagnation.
2. Poor Communication with Clients or Teams
   Clear and tailored communication is crucial. If someone regularly produces unclear work, misaligns with clients, or can’t adjust their messaging for different audiences, it can start to undermine team dynamics and client trust.
3. Not Responding to Feedback
   Feedback is constant in consulting. What matters most isn’t being perfect, but showing you can learn quickly. If someone doesn’t act on feedback or repeats the same issues, that becomes more problematic than any one performance miss.
4. Low Ownership or Lack of Proactivity
   Consultants are expected to lead their workstreams and think ahead. If someone consistently waits for direction, avoids accountability, or needs constant oversight, it can suggest they’re not ready for the autonomy expected.

Note that in my experience, these situations usually occur as a result of prolonged behaviors rather than any single instance. 

Hope this helps but keen to chat more about a specific situation in case helpful.
