MBB: McKinsey, BCG, Bain – Are They Really the Best?

If you have been looking into consulting as a career possibility, you’ve probably heard of “MBB” – McKinsey, Bain, and BCG. These three firms are the holy trinity of consulting firms and are the companies that thousands of candidates vie for. But what exactly makes them the best? In this article, we’ll be going over why the MBB firms – McKinsey, BCG, and Bain – are a cut above the rest.

Are MBB Firms Really Better Than Other Consulting Firms?

Being the “best” at anything is a subjective matter. Regardless of the industry, MBB_-McKinsey,-BCG,-Bain---Are-They-Really-the-Best_, mbb, mbb firms, McKinsey consulting, BCG consulting, Bain consulting, best consulting firms, top consulting firmswhether it’s fashion, sports, or business, people will always have their own opinions. Besides MBB, there are plenty of other notable consulting firms that have a lot going for them, such as Deloitte Consulting, which actually boasts higher annual consulting revenue than Bain.

However, the “greats” of any industry always becomes the “greats” for their excellence amongst their peers. When it comes to consulting, there are several reasons why MBB exists in its own tier.

What Makes MBB Firms Better?

Let’s dive straight into the unique aspects of MBB that make them stand out from the rest of the pack.

Focus on Strategy

By and large, McKinsey, BCG, and Bain are known for their expertise in helping clients develop organizational strategy. Strategy work is considered to be the most challenging of all types of consulting because you are dealing with the unknown. This is in comparison to implementation, financial, and tech consulting projects, which are borne from the strategy that has already been decided upon.

Because they have been working on these strategy projects for so long, MBB have established innovative ways to help their clients. They are the pioneers in business strategy and have created frameworks (i.e. the BCG Matrix) and ways of thought (i.e. McKinsey’s Pyramid Principle) that are implemented throughout the business world. MBB are also able to draw upon their rich experience with strategy projects to recognize patterns and use precedents to best help their clients.

Speed to Solution

MBB are known for the limited scope of their projects. This enables speed to solution, as anything that falls outside of the scope of the project is ignored. MBB also bill by the project (not by the hour), so consultants are incentivized to find the best solution in the shortest amount of time.

Long-Standing Client Relationships

McKinsey consulting, BCG consulting, and Bain consulting have decades and decades of experience helping businesses solve their hardest problems. When the largest Fortune 500 companies have to make a decision on which consulting firm to hire for their next project, it’s easier for them to choose one of the firms they’ve worked with before.

McKinsey consulting, BCG consulting, and Bain consulting are not only the best consulting firms, they also work with clients who are titans of their own industries. This ultimately translates to more interesting consulting projects, as the lion’s share of the best companies in the world hire MBB for their business needs. As an MBB consultant, you’ll be exposed to the smartest management teams and most interesting and complex problems on a global scale.

The cycle continues as consultants from McKinsey, Bain, and BCG leave to become business leaders in their own right. Guess who they will hire when their companies or divisions need consulting help?

Prestige and Rich History

MBB consistently rank amongst not only the best consulting firms to work for but also the best companies to work for, period. With their long and rich history, MBB are the most prestigious of all consulting firms with brand names recognized throughout the world.

Other consulting firms may try to emulate MBB, but they can never copy the rich history that each firm has. Firms that stand the test of time continue to exist because they are able to outmaneuver their competitors and maintain a consistent level of excellence. By joining MBB, you are joining historic firms with outstanding reputations.

Attractive Exit Opportunities

Having McKinsey consulting, BCG consulting, or Bain consulting on your resume will instantly provide you with credibility as you pursue opportunities throughout your career. Even though MBB provide amazing opportunities for personal and professional development, consulting is not everyone’s life goal. These firms recognize that and encourage consultants to pursue their interests and passions. For instance, Bain encourages its consultants to step away from consulting and spend several months working in externships across various industries.

Most firms also love hiring ex-MBB consultants because they know how rigorous both the recruiting process and projects are at MBB. As a result, once you leave MBB, you are provided with exit opportunities that are harder to come by compared to having a background at other consulting firms. MBB consultants exit to the best business schools and most coveted corporate positions across all industries.

Notable Alumni

McKinsey, BCG, and Bain have a great reputation for maintaining excellent relationships with their alumni. It’s actually quite a smart long-term strategy because many ex-MBB consultants eventually end up being executives at some of the largest companies in the world. These relationships are important when the best consulting firms are pitching for a project. Here are some of the notable alumni from MBB:

Are There any Disadvantages to working at MBB?

With the good, there is the bad. An experience at MBB isn’t all sunshine and rainbows. While most MBB consultants value and don’t regret the experience, there still are tradeoffs that come with working at the best consulting firms in the world.

Work-Life Balance At MBB Firms

Your work-life balance will differ widely from project to project. However, you are on the road – a lot. And in your first year, you don’t have any control of your schedule. You won’t be working consistent 80-100 hour weeks like investment bankers, but there will be days when you have to burn the midnight oil. This is especially true when you have a big upcoming deliverable.

Up or Out Culture

Simply put, there aren’t enough senior positions for all aspiring consultants. As a result, there is what’s known as an “up or out” culture at MBB. This means that you either get promoted to the next level or you are phased out. These “up or out” promotion points come every 2-3 years. Many consultants choose to leave for other opportunities at that first promotion point, regardless of whether they have been offered a promotion or not.

Intense Work Culture

Regardless of whether you find the work stimulating, being a consultant at MBB is not for the faint of heart. McKinsey, BCG, and Bain have a strong culture of feedback and constructive criticism, meaning that you’ll need to develop some thick skin.

These are very human capital driven firms, and very little will slip through the cracks. In fact, you’ll have a professional review every 1 month, 3 months, 6 months, 12 months, and at the end of every project. That’s a lot of feedback! Of course, you’re allowed to make mistakes. However, you’re expected to learn from them quickly to demonstrate your growth.
