Types of Consultants: 10 Specializations Explained

Q: What degree do you need to become a consultant?

There is no single required degree. Top firms like McKinsey recruit from all academic backgrounds. That said, degrees in business, economics, engineering, and STEM fields are most common. An MBA from a top business school is a common entry point for experienced professionals.

Types of consultants range from strategy and management consultants who advise CEOs on billion-dollar decisions to IT consultants who lead digital transformations and HR consultants who reshape company cultures. The global consulting industry generates over $300 billion in annual revenue, according to Statista, and that figure keeps growing as businesses face increasingly complex challenges.

This guide breaks down the 10 most common types of consultants, what each one actually does day to day, the salaries you can expect, and the top firms hiring in each specialization. Whether you are exploring consulting as a career or trying to figure out which type fits your strengths, this article will help you make that decision.

But first, a quick heads up:

McKinsey, BCG, Bain, and other top firms accept less than 1% of applicants every year. If you want to triple your chances of landing interviews and 8x your chances of passing them, watch my free 40-minute training.

What Are the Main Types of Consultants?

There are 10 major types of consultants in the business world. Each specialization focuses on a different set of problems, requires different skills, and pays differently. Based on my experience at Bain and years of coaching candidates, here is how the consulting landscape breaks down.

The table below gives you a quick snapshot of all 10 types. I will go deeper on each one in the sections that follow.

Type	Primary Focus	Salary Range	Top Firms	Growth Rate
Strategy	Corporate strategy, M&A, market entry	$100K–$200K+	MBB	High
Management	Org performance, change management	$90K–$180K+	MBB, Big 4	High
Operations	Process efficiency, supply chain	$85K–$160K+	MBB, Kearney	Moderate
IT / Technology	Digital transformation, systems	$80K–$170K+	Accenture, IBM	Very High
Financial Advisory	M&A, restructuring, tax, risk	$85K–$175K+	FTI, Alvarez	High
HR	Talent, culture, org design	$75K–$140K+	Mercer, Aon	Moderate
Economic	Litigation, antitrust, regulation	$90K–$180K+	NERA, Cornerstone	Moderate
Marketing	Brand, digital strategy, growth	$70K–$150K+	Prophet, Kantar	High
Risk & Compliance	Regulatory, cybersecurity, audit	$80K–$160K+	Big 4, Kroll	Very High
Implementation	Execution, change, system rollout	$80K–$155K+	Big 4, Capgemini	High

Salary ranges above are for U.S.-based consultants across all experience levels, based on Glassdoor and LinkedIn salary data. Entry-level roles start near the bottom of each range, while senior consultants and managers push toward the top.

What Does a Strategy Consultant Do?

Strategy consultants advise C-suite executives on the highest-stakes decisions a company faces. Think market entries worth hundreds of millions of dollars, mergers and acquisitions, competitive positioning, and long-term corporate direction. According to a Harvard Business Review analysis, strategy consulting projects drive measurable revenue impact for about 70% of Fortune 500 clients.

This is the type of consulting most people picture when they hear the word "consultant." In my years at Bain, strategy work meant flying to a client's headquarters on Monday morning, spending the week analyzing data and pressure-testing hypotheses, and presenting findings to the CEO by Friday. The pace is intense, but the exposure to senior leadership is unmatched.

Strategy consultants typically work on projects lasting 4 to 12 weeks. The work is heavily analytical and relies on structured problem-solving, financial modeling, and market research. You spend more time advising than implementing. Once the recommendation is delivered, the client's internal team usually handles execution.

What Are the Top Strategy Consulting Firms?

The top strategy consulting firms are McKinsey, BCG, and Bain, collectively known as MBB. These three firms are widely considered the most prestigious in the industry. According to Vault's annual consulting rankings, MBB has held the top three spots for over 20 consecutive years. For a deeper look at these firms, see our guide to the most prestigious consulting firms.

Beyond MBB, strong strategy practices exist at Oliver Wyman, Kearney, LEK Consulting, Strategy& (PwC), and Roland Berger. These tier 2 consulting firms offer competitive salaries and deep industry expertise, with acceptance rates typically between 5% and 15%.

What Does a Management Consultant Do?

Management consultants help organizations improve their overall performance through better processes, structures, and decision-making. While strategy consultants focus on where a company should go, management consultants focus on how to get there. According to the Bureau of Labor Statistics, management consulting is a $350 billion global industry employing over 1 million professionals worldwide.

Management consulting is the broadest category. It overlaps heavily with strategy, operations, and HR consulting. In practice, most consultants at MBB and the Big Four do management consulting work across multiple functional areas.

How Is Management Consulting Different from Strategy Consulting?

The biggest difference is scope and implementation. Strategy consultants typically work on narrow, high-level questions for the CEO. Management consultants take a broader view that includes implementation support, organizational restructuring, change management, and process improvement. Management consulting projects also tend to run longer, often 3 to 12 months.

At MBB firms, the line between strategy and management consulting is often blurred. A single project might start as a strategy question and evolve into a management engagement. The Big Four consulting firms (Deloitte, PwC, EY, and KPMG) do significant management consulting work, especially Deloitte's Strategy & Operations practice.

What Does an Operations Consultant Do?

Operations consultants improve how companies run their day-to-day business. They optimize supply chains, streamline manufacturing, cut costs, and boost productivity. According to McKinsey research, companies that invest in operations improvement see 15% to 25% cost reductions on average within the first year.

Unlike strategy consultants, operations consultants get their hands dirty. They walk factory floors, analyze production data, redesign workflows, and stay through implementation to make sure changes actually stick. Projects typically last 3 to 9 months and involve working closely with middle management and frontline employees.

Key areas within operations consulting include supply chain optimization, procurement, lean manufacturing, sales force effectiveness, and logistics. MBB firms all have large operations practices, and Kearney is particularly well known for its operations expertise.

What Does an IT or Technology Consultant Do?

IT consultants help organizations build, upgrade, and leverage technology to achieve business goals. This ranges from large-scale ERP system implementations to cloud migrations, cybersecurity overhauls, and AI strategy development. According to Gartner, worldwide IT consulting spending exceeded $65 billion in 2025, making it one of the fastest-growing consulting segments.

The day-to-day work varies widely depending on the project. An IT consultant might spend weeks mapping a company's existing tech infrastructure, identifying gaps, and recommending new systems. Or they might lead a team of developers through a multi-year digital transformation. Projects range from 3 months to over 2 years.

The largest IT consulting firm is Accenture, which generated over $64 billion in revenue in fiscal year 2024. Other major players include IBM Consulting, Capgemini, Infosys, Wipro, and Cognizant. The Big Four firms also have growing technology consulting practices, especially Deloitte and PwC.

What Does a Financial Advisory Consultant Do?

Financial advisory consultants specialize in the financial side of business challenges. Their work spans mergers and acquisitions, corporate restructuring, forensic accounting, risk management, tax strategy, and valuation. According to Statista, the global financial advisory market was valued at $55 billion in 2025.

This type of consulting attracts professionals with strong quantitative backgrounds in finance, accounting, and economics. The work is detail-oriented and often involves tight regulatory deadlines. Financial advisory consultants frequently serve as expert witnesses in litigation and provide due diligence support during M&A transactions.

Top firms in this space include FTI Consulting, Alvarez & Marsal, Houlihan Lokey, Lazard, and Charles River Associates. The Big Four also have major financial advisory practices, with Deloitte and PwC leading the pack.

What Does an HR Consultant Do?

HR consultants help organizations manage their people more effectively. They advise on talent acquisition, employee engagement, compensation and benefits design, organizational restructuring, leadership development, and culture transformation. According to Grand View Research, the global HR consulting market reached $42 billion in 2025.

HR consulting is one of the smaller segments of the industry, but it has been growing steadily. The rise of hybrid work, DEI initiatives, and talent shortages have increased demand for HR expertise. Projects range from designing a new compensation structure (a few weeks) to leading a complete organizational redesign (6 to 12 months).

The largest HR consulting firms are Mercer, Aon, Willis Towers Watson, and Korn Ferry. Many Big Four firms also offer HR consulting through their human capital practices.

What Does an Economic Consultant Do?

Economic consultants apply economic theory, data analysis, and quantitative modeling to solve legal, regulatory, and business disputes. This is a specialized niche within consulting that sits at the intersection of economics, law, and business. According to IBISWorld, the economic consulting industry generates approximately $15 billion in annual revenue in the United States.

Most economic consulting work ties to litigation. You might analyze the economic impact of an antitrust violation, calculate damages in an intellectual property case, or assess the competitive effects of a proposed merger for a government regulator. The work is heavily data-driven and often requires PhD-level expertise in economics or statistics.

Top economic consulting firms include NERA Economic Consulting, Cornerstone Research, Analysis Group, Compass Lexecon, and The Brattle Group. For more on this specialization, see our economic consulting case interview guide.

What Does a Marketing Consultant Do?

Marketing consultants help companies develop and refine their marketing strategies to drive revenue, build brand awareness, and improve customer acquisition. They work on brand positioning, digital marketing strategy, customer segmentation, pricing optimization, and go-to-market planning. According to Deloitte's CMO Survey, companies spend an average of 10.1% of revenue on marketing, creating strong demand for specialized expertise.

This type of consulting has grown rapidly with the explosion of digital channels. A marketing consultant today might spend equal time analyzing social media ROI data and developing traditional brand strategy. Projects typically last 2 to 6 months and involve close collaboration with a company's CMO and marketing team.

Leading marketing consulting firms include Prophet, Kantar, Simon-Kucher & Partners (pricing), and Interbrand (brand strategy). MBB firms also take on marketing strategy projects, especially around pricing, customer experience, and digital growth.

What Does a Risk and Compliance Consultant Do?

Risk and compliance consultants help organizations identify, assess, and mitigate risks while ensuring they meet regulatory requirements. Their work covers cybersecurity risk, financial regulation, anti-money laundering, data privacy (GDPR, CCPA), and enterprise risk management. According to PwC's Global Risk Survey, 80% of companies now consider risk management a strategic priority, up from 60% five years ago.

This is one of the fastest-growing types of consulting. The increasing complexity of global regulations, rising cybersecurity threats, and stricter data privacy laws have created enormous demand. Projects range from short-term compliance audits (4 to 8 weeks) to multi-year enterprise risk transformation programs.

Top firms in risk and compliance consulting include the Big Four (especially Deloitte and EY), Kroll, Control Risks, and Protiviti. Cybersecurity-focused firms like CrowdStrike and Mandiant also compete in this space.

What Does an Implementation Consultant Do?

Implementation consultants turn strategic recommendations into reality. While strategy consultants tell a company what to do, implementation consultants make it happen. They manage the execution of new processes, technology systems, organizational changes, and business initiatives. According to a McKinsey study, 70% of large-scale transformation programs fail to reach their goals, which is exactly why implementation expertise is so valuable.

The work is hands-on and project-oriented. You might lead the rollout of a new ERP system, manage the integration of two companies after a merger, or oversee the launch of a new product line. Projects typically last 6 to 18 months and require strong change management and stakeholder communication skills.

Implementation consulting is a strength of the Big Four and large IT firms like Capgemini, Infosys, and Accenture. MBB firms do some implementation work, but they tend to focus more on strategy and hand off execution to specialized firms or the client's internal team.

How Do Salaries Compare Across Types of Consultants?

Consulting salaries vary significantly by type, firm, and experience level. Strategy consultants at MBB earn the highest compensation, while HR and marketing consultants tend to earn less at the entry level. Based on Glassdoor salary data and firm-reported compensation figures, here is a detailed breakdown.

Consultant Type	Entry Level	Mid Level	Senior Level	Partner Level
Strategy (MBB)	$100K–$120K	$150K–$200K	$250K–$400K	$1M–$3M+

HR	$70K–$90K	$100K–$140K	$150K–$230K	$400K–$1M+
Economic	$85K–$115K	$140K–$180K	$220K–$350K	$600K–$1.5M+
Marketing	$65K–$90K	$100K–$145K	$160K–$250K	$400K–$1.2M+
Risk & Compliance	$75K–$100K	$115K–$155K	$170K–$280K	$500K–$1.5M+
Implementation	$75K–$95K	$110K–$150K	$165K–$260K	$450K–$1.2M+

These figures include base salary plus typical performance bonuses. Strategy consultants at MBB consistently earn the highest total compensation at every level. According to publicly reported Glassdoor data, a first-year consultant at McKinsey earns approximately $112,000 in base salary plus a $35,000 performance bonus.

How Do You Choose the Right Type of Consulting?

Choosing the right type of consulting comes down to three things: your skills, your interests, and your long-term career goals. Having coached hundreds of candidates at Bain and beyond, I have seen people thrive in every specialization. The key is matching your natural strengths to the right environment.

What Skills Does Each Type of Consulting Require?

If You Are Strong In...	Consider This Type	Why It Fits
Analytical thinking, structured problem-solving	Strategy or Management Consulting	These roles demand the ability to break down ambiguous problems and build logical frameworks quickly
Quantitative analysis, financial modeling	Financial Advisory or Economic Consulting	Heavy emphasis on numbers, data analysis, and financial expertise
Process optimization, detail orientation	Operations or Implementation Consulting	You will map workflows, identify bottlenecks, and drive measurable efficiency gains
Technology, systems thinking	IT / Technology Consulting	You need to understand both the technical and business side of digital transformation
Interpersonal skills, organizational psychology	HR Consulting	The work centers on people, culture, and organizational behavior
Creative thinking, data-driven marketing	Marketing Consulting	Combines analytical rigor with creative strategy to drive growth
Regulatory knowledge, risk assessment	Risk & Compliance Consulting	Requires deep understanding of regulations and the ability to design control frameworks

Which Type of Consulting Pays the Most?

Strategy consulting at MBB firms pays the most at every career level. First-year MBB consultants earn $110,000 to $120,000 in total compensation, according to Glassdoor data. By the partner level, MBB compensation routinely exceeds $1 million and can reach $3 million or more at senior partner levels. Financial advisory and economic consulting also pay well, especially at senior levels where profit-sharing becomes significant.

That said, compensation should not be the only factor. According to a Bain alumni survey, the majority of former consultants said that the type of work mattered more than the paycheck when choosing their specialization. Pick the type that energizes you, and the money will follow.

How Do You Break into Consulting?

Breaking into consulting follows the same core process regardless of which type you choose. You need a strong resume, targeted networking, and thorough interview preparation. Most consulting firms use case interviews as the primary assessment tool, though the format varies by firm type.

Strategy and management consulting firms (MBB, Big Four, tier 2) rely heavily on case interviews and behavioral interviews. Economic consulting firms use cases rooted in economics and data analysis. IT and implementation firms may focus more on technical skills and project management experience. HR and marketing consulting firms often emphasize industry expertise and client relationship skills.

For a complete step-by-step breakdown, see our guide on how to get into consulting. If you want to learn what consultants actually do on a daily basis, that guide covers the specifics for each type.

If you want to learn case interviews quickly, my case interview course walks you through proven strategies in as little as 7 days. It covers every case type you will see at MBB and beyond.

Frequently Asked Questions

What is the most common type of consultant?

Management consulting is the most common type. According to industry data from Consultancy.org, management consultants make up over 50% of all consultants worldwide. This is because "management consulting" is an umbrella term that includes strategy, operations, and HR consulting work.

Can you switch between types of consulting?

Yes. Switching between consulting types is common, especially early in your career. Many consultants start in one specialization and transfer to another within the same firm. Moving from strategy to operations or from management consulting to implementation consulting is especially common. Switching becomes harder at senior levels because your expertise and client relationships become more specialized.

Do all types of consultants do case interviews?

Most do, but the format varies. MBB and tier 2 strategy firms use traditional business case interviews. Economic consulting firms use cases grounded in economics and data analysis. IT and implementation firms may use technical assessments or project management scenarios instead of traditional cases. HR and marketing firms often prioritize behavioral interviews and experience-based questions.

What type of consultant makes the most money?

Strategy consultants at MBB firms earn the highest compensation at every level. According to Glassdoor data, a first-year MBB consultant earns approximately $112,000 to $120,000 in total compensation. Partners at MBB firms earn $1 million to $3 million or more annually. Financial advisory partners at firms like Alvarez & Marsal and FTI Consulting also earn well into seven figures.

What is the difference between a consultant and a freelancer?

A consultant provides expert advice to solve specific business problems, typically using structured methodologies and frameworks. Consultants are generally hired for their strategic thinking and analytical skills. A freelancer is a self-employed professional who performs specific tasks or delivers specific outputs, often following the client's direction. The key difference is that consultants tell clients what to do, while freelancers do what clients tell them.

What degree do you need to become a consultant?

There is no single required degree. According to McKinsey's hiring page, they recruit from "all academic backgrounds." That said, degrees in business, economics, engineering, and STEM fields are most common at top firms. An MBA from a top business school is a common entry point for experienced professionals. For more on this topic, see our guide on how to get into consulting.
