by Laurent Thomas | Feb 8, 2022 | Getting Hired



As a consultant, you really want to work for a top consulting firm in the world. And the good news is, there are several top consulting firms that can give your career a really big boost. But before we delve into the best and leading consulting firms, let’s first briefly go through what consulting firms are all about and what do they do. Also, we will categorize these top consulting firms and divide them into groups. Okay, so let’s get started!

What Are Consulting Firms And What Do They Do?

In layman’s terms, a consulting firm is a type of business that provides service to an individual and other businesses or organizations. This business comprises a panel of expert professionals (more commonly known as consultants) who offer their rich expertise to an individual or business, but at an agreed fee or cost.

These consultants can be hired on a per-hour or per-project basis or whatever the agreement was between the consulting firm and the client. The individual consultant has loads of experience and is qualified enough to meet the needs of his client. There are also individual consultants that specialize in one or several industries or functions and can be called up based on the specific needs that are required. Moreover, in a nutshell, when there is a crisis in a company, a consulting firm is the one that comes to the rescue when called upon.

The 4 Main Groups Of Consulting Firms

The top consulting firms are categorized into 4 main groups. These groups have been formed on the basis of certain attributes such as the size of the firm, prestige, work-life balance, employee satisfaction, culture, career growth, and diversity. The main consulting firm groups have been jotted down below.

  1. MBB Consulting Firms: The first and foremost and arguably the biggest consulting firms are grouped right at the top and are known as MBB. The MBB are initials of the three biggest consulting firms in the world – McKinsey & Company, Boston Consulting Group, and Bain & Company.
  2. The Big 4: The Big 4 consulting firms are deemed to be pretty large in size and have global recognition as well. But in comparison to MBB, their project prices and prestige put them slightly below in the pecking order. While the MBB are pure consulting players, the Big 4 are accounting firms that went into consulting. Thus, the Big 4 consulting firms comprise of 4 firms – Deloitte, PricewaterhouseCoopers, Ernst & Young, and KPMG.
  3. Tier 2 Consulting Firms: This group includes consulting firms that come under the large to the medium-sized consulting firm category, and are termed as Tier 2 consulting firms. Moreover, they do the same work as MBB firms and the Big 4 firms and earn perhaps the largest revenues in the world. The Tier 2 consulting firms are – Accenture, Roland Berger, LEK, and Oliver Wyman.
  4. Boutique Consulting Firms: The last group of consulting firms is known as boutique consulting firms because of their small size. These firms generally employ less than 500 employees and handle smaller specialized projects. And despite being smaller, they are still known to be competitive when it comes to comparing them with the top consulting firms. Some examples of boutique consulting firms are – Cornerstone Research, Putnam Associates, and The Keystone Group.
