- MBB firms hire experienced professionals into generalist consulting roles, expert or specialist consulting roles, and specialist units with technical tests. Identify which path you are applying for before you prepare.
- Firms publish experience ranges, not formulas. BCG North America, for example, describes Associates as typically having up to four years of full-time experience and Consultants as having four or more years or an advanced degree. Your final level depends on the role and on how your experience translates into consulting work.
- The case is still a case. Industry expertise helps you form hypotheses, but interviewers assess structure, numbers, judgement and synthesis, as they do for any candidate.
- Your motivation gets more scrutiny. Prepare a credible "why consulting, why now, why this firm" that shows you understand the job, without promising to stay forever.
- With a full-time job, preparation has to be targeted: a diagnosis of your gaps early, short daily drills and a few realistic mock interviews beat a long list of solo cases.
Experienced hire consulting candidates bring something graduates cannot: years of real decisions, clients, teams and results. They also face a different set of risks. Their case skills may be rusty or never trained, their stories can drown in industry detail, and interviewers ask harder questions about why they are moving now.
This guide covers the whole process for candidates with work experience, whether you are moving from industry, the public sector, another consultancy or after an MBA with several years behind you. It separates what McKinsey, BCG and Bain publish from what candidates report and from the recruiting experience of CasePreparation's coach, Franco Borgonovo. Franco spent ten years at BCG, from intern to Principal, and interviewed and selected candidates as a global lead recruiter, including many experienced candidates and candidates for BCG X, BCG Platinion and INVERTO. He still works with BCG as an official coach for new hires in BCG's Consulting Foundation Training. CasePreparation is independent and is not affiliated with McKinsey, BCG or Bain.
Who counts as an experienced hire
Consulting firms usually separate candidates into campus recruiting (undergraduates and MBA students) and experienced or lateral recruiting (working professionals). If you are working and not enrolled in a degree, you generally apply through the experienced channel, even with only two or three years of experience. BCG's North America page, for example, asks experienced candidates to be working professionals who are not currently pursuing a degree and who can start within three to four months.
The channel matters more than it seems. Experienced recruiting is usually continuous rather than tied to a campus calendar, roles are posted for specific offices and levels, and recruiters often have fewer open positions to fill at any time. BCG asks experienced candidates to apply for one position at a time, to show focus; its North America page asks you to choose the single role that best fits your background and up to two office preferences.
How consulting levels work for experienced hires
The first question most experienced candidates ask is: at what level would I join? The honest answer is that no firm converts years into a level automatically. What firms publish are typical profiles for each role.
The generalist ladder
The table below shows the first levels of the generalist consulting track, with the titles commonly used. Titles vary by office, and some firms have intermediate steps, so use it to read job postings, not to predict your offer.
| Typical role | McKinsey | BCG | Bain |
|---|---|---|---|
| Entry analyst role | Business Analyst | Associate | Associate Consultant |
| Post-MBA or equivalent | Associate | Consultant | Consultant |
| First team-lead role | Engagement Manager | Project Leader | Case Team Leader |
BCG's North America page gives a concrete example of how a firm describes the first two roles for experienced hires. It says Associates typically have zero to four years of full-time work experience and do not need prior consulting experience. Consultants generally have four or more years of professional experience, an advanced degree such as an MBA or PhD, or both; consulting experience is valued but not essential. The page also signals what each role looks for: motivation to grow, learn and have an impact for Associates, and depth in a field or function and readiness for complex strategic problems for Consultants.
How to find the roles you can credibly target
Years of experience are only one input. Recruiters look at what your experience lets you do in a consulting team from the first week. Four questions help you place yourself:
- What do the job postings ask for? Read the requirements for each level in your target office and compare them honestly with your profile: years, degree, industry or functional depth.
- What have you owned? Running your own piece of analysis and presenting it is the core of the entry and post-MBA roles. Leading a team, a client relationship and a budget is closer to a team-lead role.
- How client-facing has your work been? Experience of advising senior people, managing stakeholders or selling ideas transfers more directly than deep technical work done alone.
- Is your value general or specific? If your strength is deep knowledge of an industry or function, an expert or specialist role may fit better than the generalist ladder.
Which role and level am I being considered for, and is it confirmed before the interviews or after? Is the role on the generalist track or an expert track? Which assessments and how many interview rounds should I expect? Who will interview me? Recruiters answer these questions routinely, and the answers tell you exactly what to prepare.
A common mistake is to treat the level as a negotiation about your current title. Interviewers assess you against the role you are interviewing for. A strong performance at the right level is worth far more than a weak one at a level that looked better on paper, so the level conversation is best had early and openly with the recruiter.
Generalist, expert and specialist paths
Experienced professionals can join MBB firms through three broad paths. They differ in what you will do and in what the interviews can include.
| Path | Who it suits | What the interviews can include |
|---|---|---|
| Generalist consulting | Strong problem solvers who want to work across industries and topics | Online assessment in many processes; case and personal interviews |
| Expert or specialist consulting roles | Deep knowledge of an industry or function | Case and personal interviews, often with an interview on your expertise |
| Specialist units and technical roles | Engineers, data scientists, designers, IT and procurement specialists | Technical tests, live coding, technical or IT cases, plus business and fit interviews |
The firms describe these paths in their own words:
- McKinsey says most consulting roles include McKinsey Solve, its problem-solving assessment, and that technical roles may include a hands-on technical assessment. Client-facing candidates typically have Personal Experience Interviews and Problem-Solving Interviews, and some roles add an Expertise Interview on how your experience and skills fit the role.
- BCG says it hires experienced professionals with niche skills or deep industry knowledge into specialist and expert consulting roles, including lateral hires from other consulting firms. BCG's specialist units, such as BCG X, BCG Platinion and INVERTO, run their own processes with technical or sector-specific cases.
- Bain says interviews are tailored to each role and that every candidate for a role gets the same questions. Depending on the role, formats can include a conversation with future colleagues, a review of your past work, a case or coding challenge, or a written assignment, usually with about three days to complete.
Whichever path you choose, expect a personal interview and some form of problem solving. Expert roles rarely remove the case; they add a conversation about your expertise.
The specialist guides explain BCG X interviews, BCG Platinion interviews and INVERTO interviews in detail.
How to present your experience in the application
BCG says it assesses experienced candidates on the impact they have had over their career and how they have contributed. That is a useful lens for any MBB application. Your CV should let a screener see, in under a minute, problems you solved, decisions you drove and results you can measure.
"Responsible for procurement of electronic components; managed relationships with key suppliers; participated in cost-saving initiatives."
"Led renegotiation of the company's largest component contract (€45m a year): built a should-cost model, ran a tender with four suppliers and secured a 6% price reduction, adopted as the template for two other categories."
The weaker bullet lists responsibilities that every buyer has. The stronger one shows a problem, the analysis behind it, a measurable result and influence beyond the candidate's own scope, which is what consulting work looks like.
Three more points matter for experienced candidates. Translate internal jargon and product names into plain language. Show progression, so the screener sees a career that moves towards more responsibility. Keep the CV short enough to read quickly: one page is usual for early-career candidates, and two pages are acceptable when you have long and relevant experience.
What changes in the interviews
The structure of the interviews is usually the same as for graduates: a case and a personal or fit part, often in the same hour, across two or more rounds. BCG's North America experienced-hire page says its interviews are case interviews, and McKinsey's interview page does not describe a separate process for experienced hires. What changes is the standard you are held to.
Interviewers calibrate their expectations to the role. For a candidate with eight years of experience applying as a Consultant, a clean case is necessary but not sufficient. Interviewers also ask themselves whether they could put you in front of a client's senior team, whether you would lead a workstream with little supervision, and whether you will enjoy a job that may look very different from your current one.
Five patterns that hold experienced candidates back
From the interviewer's side, the same patterns appear again and again with experienced candidates. None is about intelligence; all can be trained.
- Underestimating the case. Strong professionals sometimes expect their experience to carry them and prepare too little. The case format is a skill, and it needs practice.
- Answering from industry habit. Jumping to "what we did at my company" instead of structuring the client's problem from the top down.
- Depth without breadth. Going deep on one familiar lever and missing the others that a generalist would have listed in the first minute.
- Rusty maths. Mental arithmetic that has not been used without a spreadsheet for years, which shows quickly under time pressure.
- Long answers. Communication habits from internal meetings, with background first and the point at the end, instead of the answer first.
These patterns can be hard to spot on your own. A mock interview in 1:1 coaching with Franco tells you which ones apply to you, so your limited preparation time goes to the right skills.
The case: experience helps, structure decides
Your experience is a real advantage in a case if you use it to form better hypotheses and to check whether numbers are plausible. It becomes a handicap when it replaces the reasoning. The fictional example below shows the difference.
A hospital group spends €200 million a year on medicines and wants to reduce that cost without affecting patient care. You have eight years of experience in pharmaceutical distribution. How would you approach the problem?
"In my experience the best lever is renegotiating with wholesalers. At my company we saw hospital groups get 3 to 4% from consolidating their distributors, so I'd start there."
"I'd look at three things: how much medicine the group uses and whether all of it is needed, which products it buys and whether cheaper equivalents exist, and what it pays per unit, including distribution. From my years in distribution, I suspect the largest lever is product choice rather than the wholesaler margin, so I'd start by checking how much of the spend has a generic or biosimilar alternative."
The weaker opening applies one familiar lever and stops. The stronger one covers the problem first, then uses the candidate's experience to choose where to start and explains why. The interviewer sees both structure and judgement.
The interviewer then gives you two figures: about 25% of the spend is on medicines with a cheaper equivalent, and the equivalents cost about 40% less.
Spend with an equivalent: 25% × €200m = €50m
Potential saving if every switch happened: 40% × €50m = €20m a year, 10% of the total
The calculation is simple; the judgement is in what comes next. A strong candidate says that €20 million is the ceiling, not the forecast, because doctors will not switch every patient, some contracts run for years and some equivalents may not be accepted for clinical reasons. "If half of the switches happen in the first year, we're at about €10 million, and I'd want to know which therapeutic areas carry most of the €50 million before promising more."
Notice that the answer uses the candidate's background twice: to choose the starting hypothesis and to know which barriers make a theoretical saving smaller. Neither use replaces the structure or the arithmetic.
Discussing your professional projects
Experienced candidates usually spend a large part of the personal interview on one or two real projects. Interviewers want to understand what you personally did, how you thought and how you worked with others. McKinsey says its Personal Experience Interview asks you to focus on your own role and explain your reasoning rather than just listing actions, and that it should be a conversation rather than a rehearsed presentation. The same habits work at every firm.
Prepare each project around five elements: the problem and why it mattered, your personal responsibility, the alternatives you considered, the decision and how you made it, and the result with what you learned. Then prepare for the follow-up questions, because that is where interviews are decided.
The situation
A candidate has described leading the move of a regional warehouse to a new site, finished on time and 5% under budget. The interviewer asks: "What would have gone differently if you had not been on the project?"
A weak answer
"It would probably have been delayed. I worked very hard and coordinated everyone, and the team really relied on me."
A stronger answer
"Two things. First, the original plan moved all stock in one weekend. I ran the numbers on picking capacity, saw we would miss two days of deliveries to our largest customer, and proposed moving in three waves. My manager disagreed at first, so I tested the wave plan on one product family, and it worked. Second, I negotiated with the IT team to bring the system cut-over forward a week. Without those two decisions, I think we would have had a delivery failure with that customer, which mattered more than the budget."
Why it works
The stronger answer names specific decisions, shows the analysis behind them, includes a disagreement and how it was resolved, and makes the counterfactual concrete. It is also honest: it does not claim the whole result.
Why consulting, why now, why this firm
For experienced candidates, motivation is examined more closely than for graduates. You are leaving a career with some momentum, often taking on long hours and travel, and interviewers want to know that the decision is considered. In candidate reports, senior interviewers in final rounds often push back on answers that would be acceptable from a student but sound thin after several years of work.
A credible answer has three parts:
- Why consulting: what in the job itself attracts you, linked to things you have done, for example the problems you enjoyed most in your current role.
- Why now: what has changed or what you have learned that makes this the right moment, without criticising your employer.
- Why this firm: two specific reasons, ideally from conversations with people there, the firm's work in your area or the office you are applying to.
You do not need to promise that you will stay for decades, and interviewers know when such promises are artificial. What helps is showing that you understand the job, including its demands, and that you want the work itself, not only what it might lead to.
"I've been in the same company for seven years and I feel I've learned what I can there. Consulting would give me exposure to many industries and great exit options, and I think now is the right time for a change."
"For the last three years, the part of my job I've enjoyed most has been the cross-functional projects: last year I led the review of our distribution network with finance and operations, and I liked the problem solving more than running the function day to day. Consulting would let me do that work full time, across companies. Why now: I've seen one industry from the inside in depth, so I can bring that to clients in it, and I'm ready to learn the broader toolkit while I still have that perspective fresh. I've spoken with two consultants from your operations practice about what the first year looks like, including the travel, and that's the work I want."
The weaker answer is about leaving and about exit options. The stronger one links consulting to specific work the candidate enjoyed, gives a reason for the timing that adds value for clients, and shows a realistic picture of the job.
Build your interview introduction and why consulting answer, then adapt the firm-specific part using why McKinsey, why BCG or why Bain. The fit questions guide helps you prepare the follow-ups.
A preparation plan that fits a full-time job
Most experienced candidates prepare in the evenings and at weekends. The plan below assumes about six weeks and five to six hours a week. Adjust it to your starting point: if you have never done a case, add a week at the start; if your interviews are sooner, compress the middle phase and keep the mock interviews.
| Week | On weekdays (20 to 30 minutes) | At the weekend (2 to 3 hours) |
|---|---|---|
| 1 | Mental maths; read one business article and summarise it in two sentences | Learn the case format; one full case with a partner or coach to find your gaps |
| 2 | Maths; structure one short prompt a day aloud | Two cases; draft your project stories and your motivation answer |
| 3 to 4 | Maths; chart reading; tell one story aloud and test it with "why?" | Two to three cases with feedback, focused on your recurring errors |
| 5 | Short drills on your weakest skill | Two realistic mock interviews, case and fit together |
| 6 | Light review; rehearse your introduction and motivation | One final mock early in the week, then rest |
With little time, the biggest risk is practising what you are already good at. Get an outside diagnosis early, keep a written list of your two or three recurring errors, and judge each week by whether those errors appear less often, not by the number of cases completed.
If your process includes an online assessment, such as McKinsey Solve or a BCG online case, add focused practice in the week before the deadline in your invitation. If your role includes a technical or expertise interview, set aside time to explain your most important work simply to someone outside your field.
Preparing with a former BCG recruiter
Coaching is most valuable when your time is short and you need to know exactly where to spend it. A first session gives you a realistic interview, case and fit together, followed by a diagnosis of what would hold you back at your target level and a written plan. Later sessions check whether the fixes are working under interview conditions.
Franco's recruiting experience is particularly relevant here. As a global lead recruiter at BCG he assessed experienced candidates across levels and specialist units, and he knows the questions interviewers ask about level, motivation and readiness for clients. Sessions adapt to your target firm, role and round, including final-round interviews with partners.
"I received my formal offer from BCG, as PL in the PIPE team in London. I applied the feedback and it paid off."

Frequently asked questions
Do experienced hires take the online assessment?
Often, yes. McKinsey says most consulting roles include McKinsey Solve, and BCG and Bain use online assessments in many processes. Whether yours includes one depends on the firm, office and role, so check your invitation or ask the recruiter.
Do I need an MBA to join MBB as an experienced hire?
No. BCG's North America page, for example, describes Consultants as having four or more years of professional experience and/or an advanced degree. An MBA can help career changers and gives access to campus recruiting, but it is not a requirement for experienced recruiting.
Can I apply to several roles at the same firm?
BCG asks experienced candidates to apply for one position at a time and to choose the role that best fits their background. Other firms have their own rules, so check the application page and ask the recruiter if you are unsure which role to choose.
Will my industry experience make the case easier?
It can make your hypotheses and sense checks better, especially in a case from your industry. It does not replace the structure, calculations and synthesis that interviewers assess, and cases from your own industry can tempt you to answer from habit.
How long should I prepare?
As a planning reference, about six weeks at five to six hours a week if you have done few cases, and less if you have practised before. What matters is that your recurring errors disappear, not the number of cases completed.
What if I am rejected?
BCG recommends waiting at least 12 months before reapplying, to build further experience. Use the time to work on the gaps you noticed or were told about, and check each firm's own guidance.
Final checklist
