Brief History of Big 4 Consulting Firms
Deloitte
Deloitte's origins trace back to 1845, when William Welch Deloitte founded his accounting practice in London. This global management consulting firm emerged in the 1980s, following the merger with Touche Ross, to offer a broader range of advisory services beyond traditional accounting.

The consulting division became a vital component, offering advisory services in strategy, technology, operations, and human capital. In 2002, PwC Consulting was sold to IBM and rebranded as IBM Global Business Services, but PwC re-entered the consulting market in 2009 by acquiring several advisory firms. Today, PwC Consulting is a global leader in management consulting, known for helping clients solve complex business challenges and drive transformation across various industries. Operating in over 150 countries, PwC Consulting delivers insights and solutions that enhance business performance and create value.

The accounting firm traces its roots to Harding & Pullein in 1849 and Ernst & Ernst in 1903, with the merger of Ernst & Whinney and Arthur Young & Co. forming Ernst & Young in 1989. EY Consulting emerged as a distinct service line, offering expertise in strategy, technology, operations, and human capital.

Today, KPMG Consulting is a global leader, offering comprehensive solutions to help clients navigate complex business challenges and drive innovation, with a presence in over 150 countries.
MBB vs. the Big 4
The distinction between the MBB and big 4 consulting firms is pronounced, primarily due to their foundational services and market focus. MBB firms, established leaders in the consulting industry, specialize exclusively in consulting services, with a storied history in this field — McKinsey since 1926, BCG since 1963, and Bain since 1973. These firms have developed proprietary frameworks like BCG's "growth-share matrix," McKinsey's "7-S Framework," and Bain's "Net Promoter Score," which have become fundamental in strategic business planning globally.
Big 4 consulting firms originally focused on audit and accounting services before expanding into consulting. They started offering consulting services in the 1990s, briefly sold them off in the 2000s, and then reintroduced them in the 2010s. Now, they provide a variety of services including tax, audit, and consulting, with auditing still being their main business. Their consulting capabilities often grew through acquisitions, like Deloitte buying Monitor Group and PwC acquiring Booz & Company.
On the other hand, McKinsey, Boston Consulting Group, and Bain & Company (MBB) focus solely on strategy consulting. This specialization allows these top consulting firms to charge higher fees and take a deep dive into client issues. They mainly recruit from top universities and business schools.
The Big 4’s wider range of services means they work with diverse industries and clients, from large corporations to small businesses and government bodies. Their recruitment is broad, reflecting their varied services and clientele. As some of the largest management consulting firms, they also tend to have more structured approaches to work-life balance, which can appeal to a wider range of professionals.
Implementation and Transformation
Implementation and transformation refer to the process of executing strategic plans and driving comprehensive changes within an organization to achieve specific business objectives. This involves translating high-level strategies into actionable plans, managing change, and ensuring that the desired outcomes are realized.
Professional Growth and Exit Opportunities
Career Development Paths in management consulting firms offer a spectrum of growth trajectories depending on the firm's focus and the individual's performance. MBB firms are renowned for their rigorous recruitment processes and tend to hire predominantly from top-tier universities. This selective recruitment supports their high-status branding and aligns with their premium service charges, which can range from $500,000 to $1,250,000 per strategy case. The career paths at MBB often lead to high-profile roles in industry, with many alumni moving into executive positions such as CEOs or CFOs.
Conversely, the Big 4, while slightly less prestigious, also provide substantial career opportunities. Their projects might be perceived as high volume which sometimes could imply a lower quality compared to MBB. However, they offer a variety of roles across different functional areas such as strategy, operations, and technology consulting, which are supported by their broader service offerings. The Big 4's alumni are commonly found in leadership roles within smaller market units (SMUs) or startups and also have opportunities for internal corporate roles which tend to offer a better work-life balance.

What Are the Differences in Exit Opportunities?
Exit opportunities between MBB and the Big 4 vary significantly due to their differing client engagement models and project scopes. MBB consultants often transition into high-impact roles in private equity, corporate strategy, or venture capital, leveraging their strategic consulting experience. They are also likely to launch their own ventures, reflecting the entrepreneurial spirit cultivated during their consulting tenure.
Consultants from the MBB are often the first choice for employers due to their rigorous selection process and the prestigious reputation of these firms, which signals high talent. MBB firms also offer greater exposure to attractive exit opportunities through internal career centers and job boards, providing strong support for career transitions. In contrast, the big four consulting firms do not provide the same level of support, making MBB consultants more attractive to future employers.
How to Land a Role with the Big 4 or the MBB
Don’t worry, we are not going to make you read a long technical paragraph where you will not get any substantial information at the end. Landing a role at the top consulting firms only requires you to have the following:
- Strong academic performance
- Relevant work experience
- Problem-solving skills
- Interpersonal skills
- Networking skills
- Analytical skills
- Adaptability
- Versatility
- Teamwork
- Leadership
Both MBB and Big 4 consulting firms look for candidates who demonstrate a high level of these skills – some are often assessed through rigorous case interviews. Additionally, for those aiming at MBB, showcasing experience in emerging areas like digital transformation, AI, or sustainability could be advantageous.
5 Tips to Nail Your Interviews with the Big 4 Consulting Firms
- Preparation is Key: Start by thoroughly preparing situational examples that showcase your skills and experiences. Whether these are from previous work experiences, internships, or specific projects, being able to discuss these examples fluently is crucial. It's also beneficial to prepare for basic interview questions you expect to encounter at every stage of the interview process. Understanding the consulting practices of these top consulting firms will give you an edge.
- Practice Makes Perfect: Engage in mock interviews to build confidence and reduce awkwardness during the actual interview. Utilize resources like career services or practice with a friend. Rehearsing answers to common Big 4 interview questions can significantly enhance your performance. This is particularly important when preparing for roles in strategy consulting at a global consulting firm.
- Ask Intelligent Questions: At the end of your interview, asking well-thought-out questions can leave a lasting impression. Inquire about macroeconomic trends affecting the department or new regulations that might impact the firm. This not only shows your interest but also your understanding of the industry's landscape. Demonstrating knowledge of management consulting can help you stand out.
- Showcase Your Personality: During the final stages, such as the partner interview, it’s essential to let your personality shine through. This helps the interviewers gauge if you would be a good fit within their team culturally. Remember, they are looking for someone who can not only perform well but also integrate seamlessly into their team. In strategy consulting, the ability to work well with a diverse team is crucial.
- Follow Up Thoughtfully: Sending a physical thank you card after your interview can distinguish you from other candidates. This small gesture of appreciation is rare and can set you apart, demonstrating your attention to detail and earnest interest in the position. A thoughtful follow-up can be particularly impactful in the competitive world of management consulting.
By incorporating these strategies, candidates can enhance their chances of making a memorable impression during their interviews with Big 4 consulting firms.
