For many graduates, the consulting industry is an attractive entry point into professional life. Whether you are interested in strategy consulting or management consulting, and whether your focus is on McKinsey, BCG, and Bain (MBB) or one of the Big Four, consulting offers strong development opportunities and competitive salaries. At the same time, the industry is highly diverse, with different firm cultures and areas of specialization.
So which type of consulting, which firm, and which location truly fit you best? Let’s figure it out together. 🚀
Which Consulting Firms Are the Best to Work For?
Consulting firms can be categorized by focus, specialization, service offering, and business model. Overall, they can be grouped into several main categories:
Before choosing a firm, it is important to understand its culture and working style to ensure alignment with your long-term career goals.
MBB – The Leading Tier of Consulting Firms
MBB stands for McKinsey & Company, Boston Consulting Group (BCG), and Bain & Company, the three most prestigious consulting firms worldwide. They are known for strong problem-solving capabilities, advanced analytical tools, and deep industry expertise. Through their work with global organizations, they set standards across the consulting industry and remain among the most sought-after employers.
The Big Four – Global Professional Services and Consulting Firms
The Big Four Deloitte, PwC, EY, and KPMG are among the world’s leading professional services firms. Their offerings range from audit and tax to consulting, strategy, and risk management. For graduates, they are particularly attractive due to structured entry programs, solid career development, and competitive compensation.
Tier 2 Consulting Firms – Global Reach and Strong Alternatives
Beyond the most well-known names, the consulting landscape includes Tier 2 firms, specialized consultancies, and in-house consulting teams. These firms often operate internationally, offer challenging projects, and provide strong learning opportunities. They are attractive alternatives to MBB and the Big Four for many candidates.
How Do Interviews at Top Consulting Firms Work?
Consulting interviews usually follow a clear core principle: they assess analytical skills, structured thinking, clear communication, and the ability to solve complex problems. Case interviews are at the center of the process, complemented by fit or personal interviews that focus on motivation and working style.
Despite these similarities, interview processes vary significantly by firm. MBB often uses hypothesis-driven cases, while Big Four, Tier-2, and boutique consultancies tend to emphasize more practical, industry-specific, or proprietary interview formats.

How Do Consulting Markets Differ by Region?
The consulting industry varies significantly by region. Each market is shaped by local industries, economic conditions, and cultural factors. For example, the automotive industry plays a major role in Germany, while technology and growth sectors dominate in Southeast Asia. These differences influence which consulting firms are most relevant and what working styles you can expect in each region.
