Why consulting is the single most important behavioral interview question you will face at McKinsey, BCG, Bain, and every other consulting firm. Every interviewer asks it, and your answer sets the tone for the entire interview.

 

In this guide, you will learn exactly what interviewers are looking for, the 14 best reasons to give, 6 answers you should never use, and a proven structure with word-for-word examples. Having coached hundreds of candidates as a former Bain interviewer, I have seen firsthand how a strong answer to this question can be the difference between an offer and a rejection.

 

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.

 

Why Is the "Why Consulting" Question So Important?

 

The "why consulting" question is important because it is asked in virtually 100% of consulting interviews and is often the very first question out of the interviewer's mouth. Your answer creates the first impression, and according to research on interviewer decision-making, most interviewers mentally decide whether a candidate will pass within the first 10 to 15 minutes.

 

Candidates spend hundreds of hours preparing for case interviews, but most spend less than 10 minutes preparing for this question. That is a huge missed opportunity. If you are interviewing with 10 consulting firms that each have two rounds with two interviewers, that is 40 separate interviews. If just half of your interviewers ask this question, you will answer it 20 times.

 

Investing even 30 minutes to craft a strong answer gives you a meaningful edge over candidates who wing it. In my experience coaching candidates, those who prepare a structured, genuine answer to this question consistently outperform those who treat it as a throwaway.

 

What Are Interviewers Really Looking For?

 

Interviewers use the "why consulting" question to assess four things: your understanding of the job, your structured thinking, your communication skills, and your genuine enthusiasm. A strong answer hits all four. A weak answer misses at least one.

 

Do You Understand What Consultants Actually Do?

 

Interviewers want to know that you understand what consulting actually involves on a day-to-day basis. Consulting is one of the most popular career paths among undergrads and MBAs. At top schools, roughly 20% to 30% of each graduating class applies to consulting firms.

 

Many of these applicants apply because consulting is easy to apply to (usually just a resume, no cover letter) or because they are unsure what they want to do. Interviewers need to quickly separate candidates who understand and want the job from those who applied on a whim.

 

Your answer needs to show that you know what consultants do: work on teams to solve complex business problems for clients across different industries and functions, present recommendations to senior executives, and deliver measurable results.

 

Can You Think and Communicate in a Structured Way?

 

Structured thinking is the core skill of a consultant. Interviewers assess it in case interviews, but they also look for it in your behavioral answers. If your case interview performance is structured but your answer to "why consulting" is rambling and disorganized, that raises a red flag.

 

A well-organized answer signals that you naturally think in a clear, logical way. Interviewers will also ask themselves whether they can picture you presenting to a client. If you cannot clearly explain your own motivations, they will doubt you can explain a recommendation to a CEO.

 

Are You Genuinely Enthusiastic About Consulting?

 

Enthusiasm matters more than most candidates realize. Interviewers want to see a spark when you talk about consulting. They want to see energy in your voice and a smile on your face.

 

This is not about being fake or over-the-top. It is about genuinely conveying that consulting excites you. Enthusiasm signals that you will work hard and stay engaged, even during the tough weeks of long hours and demanding client work.

 

Will You Stay Long Enough to Justify the Investment?

 

Training a new consultant costs firms significant time and money. According to internal estimates at top firms, it takes roughly 6 to 12 months before a new hire becomes fully productive. If someone leaves after 6 months, that is a net loss for the firm.

 

Interviewers use this question to gauge whether you will stay for at least 2 to 3 years. Candidates who cite genuine, intrinsic motivations (solving problems, working with teams, building skills) tend to stay longer than those motivated primarily by pay or exit opportunities.

 

What Are the Best Reasons to Give for "Why Consulting"?

 

The best reasons for why consulting combine genuine personal motivation with a clear understanding of what the job offers. You should pick three reasons that resonate with your actual experiences and goals. Here are 14 strong reasons to choose from:

 

• You want to make a significant impact by working with executives at billion-dollar companies on their most challenging business problems

 

• You enjoy the variety of solving business problems across multiple industries and functions

 

• You see consulting as the fastest way to build a strong toolkit of both hard skills and soft skills to become a business leader

 

• You see consulting as the best training ground to eventually start your own company

 

• You enjoy working closely with teams on tough, intellectually stimulating challenges

 

• You want to get an insider view of how large companies are run and operated at the highest levels

 

• You want to develop deep knowledge and expertise in a particular industry or function

 

• Working across industries will help you narrow down your interests and decide on a long-term career path

 

• You value the significant mentorship and personal development that consulting firms provide

 

• Consulting offers the opportunity to manage others and lead teams at a relatively early career stage

 

• You find excitement in servicing clients and delivering tangible value to their businesses

 

• You are excited to travel and work in different locations around the world

 

• You do not have a traditional business background and see consulting as the best path to transition into a business role

 

• You enjoy working with and learning from exceptionally bright and driven people

 

The strongest answers personalize these reasons. Do not just list generic motivations. Tie each reason to a specific experience from your academic or professional life that shaped why you value that particular aspect of consulting.

 

What Reasons Should You Avoid?

 

Some reasons for wanting consulting, while honest, will hurt you in an interview. These signal to the interviewer that you are interested in consulting for the wrong reasons. Here are 6 answers you should never give:

 

Bad Reason	Why It Fails
You want to earn a lot of money	Signals you will leave for the next highest-paying opportunity. Consulting firms know candidates motivated primarily by money rarely last more than a year.
You want a prestigious brand name on your resume	Tells the interviewer you see the firm as a stepping stone, not a destination. This makes them question whether you will be engaged and committed.
You want the firm to sponsor your MBA	Many firms do sponsor graduate school, but leading with this reason says your primary interest is in the benefit, not the work itself.
You want access to consulting exit opportunities	Exit opportunities are a real perk, but mentioning them in an interview tells the interviewer you are already planning to leave.
You enjoy traveling, staying in nice hotels, and eating fancy meals	This makes you sound like you are more interested in the perks than in the actual work of solving client problems.
You are unsure what you want to do, so consulting seems like a safe choice	This is perhaps the most common honest reason, but it signals low commitment and lack of direction. Interviewers want to hire people who are actively choosing consulting, not defaulting to it.

 

To be clear, many of these are real reasons people go into consulting. There is nothing wrong with wanting good pay or exit opportunities. But these are not the reasons you should share in an interview. Lead with your genuine intrinsic motivations instead.

 

How Should You Structure Your "Why Consulting" Answer?

 

The best "why consulting" answers follow a simple three-part structure. This mirrors how consultants communicate: lead with the conclusion, support it with evidence, and close with a clear summary. In my experience, candidates who use this structure consistently score higher than those who ramble.

 

Part 1: Opening statement. State clearly that consulting is your top career choice. This immediately tells the interviewer you are committed and focused.

 

Part 2: Three reasons with personal evidence. Give three specific reasons why consulting appeals to you. For each reason, briefly connect it to a real experience from your background. This is what separates a great answer from a generic one.

 

Part 3: Closing statement. Reiterate that consulting is the best fit for your professional goals. This bookends your answer and leaves the interviewer with a clear takeaway.

 

Your entire answer should take about 60 to 90 seconds. Anything shorter feels underprepared. Anything longer risks losing the interviewer's attention. According to former McKinsey interviewers, the ideal length is roughly one minute.

 

If you want a structured way to prepare for this and every other consulting behavioral interview question, my fit interview course covers 98% of the questions you could be asked in about 3 hours.

 

What Does a Great "Why Consulting" Answer Sound Like?

 

Below are three word-for-word example answers tailored to the most common candidate profiles: undergrads, MBAs, and career changers. Use these as inspiration to craft your own personalized answer. Do not copy them word-for-word.

 

Example Answer for Undergraduate Candidates

 

"Consulting is my top career choice for three reasons.

First, I want to work with executives at major companies on their toughest business problems. During my internship at a Fortune 500 retailer, I helped the strategy team analyze a market entry decision, and I realized that the work consultants do is exactly what energized me most.

Second, I thrive on variety. I loved that my economics coursework took me from healthcare policy to tech industry dynamics in the same semester, and consulting offers that same diversity in a professional setting.

Third, I want to build a strong foundation of business skills early in my career. Consulting is widely recognized as one of the fastest ways to develop structured problem solving, client management, and analytical skills that transfer to any future role.

For these reasons, I believe no other career path fits my goals as well as consulting."

 

Why this works: It follows the three-part structure, includes personal evidence (the internship, the coursework), and avoids generic filler. The answer takes about 50 seconds to deliver.

 

Example Answer for MBA Candidates

 

"Consulting is my top career choice for three reasons.

First, in my previous role leading operations at a mid-size manufacturing firm, I often wished I could bring in outside expertise to solve cross-functional problems faster. Consulting lets me be that outside expert for multiple companies.

Second, I want to deepen my knowledge in supply chain strategy. Consulting offers the chance to work on dozens of supply chain projects across industries in just a few years, which would take decades to see in a single company.

Third, I value the mentorship and feedback culture that top consulting firms are known for. At my previous company, formal reviews happened once a year. Consulting firms provide detailed performance feedback after every single engagement. That kind of rapid development is exactly what I am looking for at this stage of my career.

Consulting is the best fit for where I want to go professionally."

 

Why this works: It connects each reason to specific professional experiences, demonstrates deep knowledge of how consulting works (project-based feedback cycles), and shows a clear career direction.

 

Example Answer for Career Changers

 

"Consulting is my top career choice for three reasons.

First, after six years in software engineering, I have developed strong analytical and problem-solving skills, but I want to apply them to broader business challenges rather than purely technical ones. Consulting is the best bridge between my technical background and a business leadership career.

Second, I want exposure to multiple industries. As an engineer, I only saw the tech sector. Consulting will give me the chance to work across healthcare, financial services, and consumer goods, which will help me decide where to focus long-term.

Third, I am drawn to the collaborative, team-based nature of consulting. The projects I enjoyed most as an engineer were the ones where I worked cross-functionally with product managers, designers, and executives. Consulting is built around that kind of collaboration.

I am confident that consulting is the right next step for my career."

 

Why this works: It directly addresses the "why leave your current field" question that interviewers will have. It frames the career change as a deliberate, well-considered decision rather than running away from something.

 

How Should You Deliver Your Answer?

 

Great content and structure are not enough. You also need to deliver your answer well. In my experience interviewing candidates at Bain, the difference between a good answer and a great answer almost always came down to delivery. Here are three things to focus on.

 

Be genuine and credible. When people are not telling the truth, their body language and voice change. Interviewers can detect when a candidate is reciting generic reasons they found online. The solution is simple: only give reasons you actually believe. If you genuinely do not care about working with teams, do not list it as a reason.

 

Show enthusiasm through energy. This does not mean being loud or over-the-top. It means speaking with energy, making eye contact, and showing that consulting excites you. If you are naturally reserved, you will need to push yourself slightly beyond your comfort zone to match the energy level that interviewers expect.

 

Practice, but do not memorize word-for-word. Practice your answer 5 to 10 times in front of a mirror or with a friend. This eliminates stuttering and hesitation. But do not memorize every word. Over-rehearsed answers sound robotic and undermine your credibility. You should know your three reasons and the general flow, but the exact wording should feel natural each time.

 

If you want personalized feedback on your delivery, my 1-on-1 coaching helps you improve roughly 5x faster than solo practice. I can tell you exactly where your answer is strong and where it needs work.

 

What Variations of "Why Consulting" Might You Hear?

 

Interviewers do not always use the exact words "why consulting." You may hear several different phrasings that all test the same thing. Preparing for these variations ensures you are not caught off guard. Here are the most common versions:

 

Question Variation	How to Adapt Your Answer
What attracts you to consulting?	Use your standard 3-part answer. This is the most direct synonym.
Why consulting over investment banking?	Emphasize collaboration, variety of problems, and client impact. Contrast with the transaction-focused, individual nature of IB.
Why consulting instead of tech or startups?	Highlight exposure to multiple industries, structured skill development, and working with senior executives across sectors.
Why consulting over staying in your current role?	Explain what consulting offers that your current role cannot: broader impact, faster learning, cross-industry exposure.
What do you find most exciting about consulting?	Pick your single strongest reason and go deeper on it with a personal story. Keep the other two reasons brief.

 

The key insight is that your core answer stays the same. You are just adjusting the emphasis based on the specific question. If they ask about consulting versus banking, lean harder on the reasons that differentiate consulting from finance.

What Are the Most Common "Why Consulting" Mistakes?

 

Having interviewed hundreds of candidates, I have seen the same mistakes over and over. Avoiding these will immediately put you ahead of most applicants.

 

Mistake	Why It Fails	What to Do Instead
Giving generic reasons	"I like problem solving" could apply to any job. It tells the interviewer nothing specific about you or consulting.	Tie each reason to a specific personal experience that shows why consulting specifically appeals to you.
Listing reasons without evidence	A list of reasons without stories feels hollow and rehearsed. Interviewers want to see that your motivations come from real experiences.	For each reason, include a 1-2 sentence example from your background.
Talking too long	Answers over 2 minutes lose the interviewer's attention and suggest you cannot communicate concisely.	Keep your answer to 60-90 seconds. Practice with a timer.
Mentioning money or prestige first	Signals you are motivated by external rewards rather than the actual work of consulting.	Lead with intrinsic motivations. If you value pay, that is fine, just do not say it in the interview.
Sounding overly rehearsed	Word-for-word memorization makes you seem robotic and insincere.	Memorize your 3 key reasons and supporting examples, not the exact words.
Not personalizing your answer	An answer anyone could give is an answer no one remembers. Interviewers hear the same generic responses all day.	Include details only you could share: specific projects, classes, conversations, or experiences.

 

How Does "Why Consulting" Differ from "Why This Firm"?

 

Many candidates confuse these two questions, but they test different things. "Why consulting" asks why you want to work in the consulting industry. "Why this firm" asks why you want to work at that specific company. You need separate answers for each.

 

Your "why consulting" answer should focus on the nature of consulting work itself: the problem-solving, the variety, the team environment, the skill development. This answer stays roughly the same no matter which firm you are interviewing with.

 

Your "why this firm" answer should focus on what makes that specific firm unique: its culture, its industry focus areas, specific people you have met, its approach to staffing or training, or its values. This answer should change for each firm you interview with.

 

Here is a simple way to think about it. If your answer to "why McKinsey" could also work for "why BCG," it is not specific enough. You need concrete details about the firm. Mentioning a conversation with a current consultant at that firm is one of the strongest ways to personalize this answer.

Frequently Asked Questions

 

How Long Should Your "Why Consulting" Answer Be?

 

Your answer should be 60 to 90 seconds long. This is enough time to cover your opening statement, three reasons with brief evidence, and a closing statement. Anything under 30 seconds feels unprepared. Anything over 2 minutes risks losing the interviewer's attention.

 

Should You Mention Compensation as a Reason for Consulting?

 

No. While consulting compensation is strong (total first-year pay ranges from roughly $110K for undergrads to $250K for MBAs at top firms), mentioning money signals that you are more interested in the paycheck than the work. Interviewers know the pay is good. They want to hear why the work itself excites you.

 

Can You Use the Same Answer for Every Firm?

 

Yes, your core "why consulting" answer can stay the same across firms. This question is about the industry, not the specific firm. However, be ready for the follow-up "why this firm" question, which requires a unique answer for each company. For tips on preparing your tell me about yourself and other behavioral answers, see our guide.

 

What If You Genuinely Do Not Know Why You Want Consulting?

 

If you are unsure, spend time researching the career before your interview. Talk to current consultants, read about what the day-to-day work is like, and attend info sessions. You need to find at least three genuine reasons before you interview. If you cannot, consulting may not be the right fit for you right now, and that is okay.

 

When in the Interview Is "Why Consulting" Typically Asked?

 

This question is almost always asked at the beginning of the interview, before the case interview starts. It is part of the behavioral or fit portion of the interview. At McKinsey, it typically comes up during the Personal Experience Interview. At BCG and Bain, it usually appears in the first 5 to 10 minutes of the interview.

 

Should You Tell a Story or List Reasons?

 

The most effective approach combines both. Use a structured list of three reasons (which consultants expect and respect), but embed a brief personal story or example within each reason. This gives you the clarity of a structured list with the memorability of storytelling.
