Consulting, from the outside in.
The graduate route with the widest exits and the most explicit ladder, and an interview that tests a performance skill rather than a body of knowledge. The firms by type, the ladder from analyst to partner, how to prepare, and how it compares, on one page.
1.The job and the ladder
Five places a consultant can work, and five levels that are the same in each. Stages mark where people join from other careers and where they leave for them.
Where you work
Strategy Consulting
Where to play and how to win, for the people who decide it. Small teams, short engagements, senior clients.
Spring insight → summer internship → graduate analyst
Where you work
Deals & Transaction Services
Commercial and financial diligence for corporate and private equity buyers. The closest consulting gets to banking.
Graduate scheme, often with an accounting qualification
Where you work
Operations & Performance
Making the business run: supply chain, procurement, manufacturing, service operations. Measurable and unglamorous.
Graduate analyst, or from an industry role
Where you work
Technology & Digital Consulting
Systems, data and increasingly AI deployment. The largest part of the industry by revenue and by headcount.
Graduate scheme, large intakes
Where you work
Economic Consulting
Competition cases, regulatory pricing and damages. Genuinely technical, and the client is often a regulator or a court.
Direct from an economics degree or postgraduate study

| Level | Stage | When |
|---|---|---|
| Consulting Partner | senior | Ten to fifteen years in |
| Associate Partner / Principal | senior | Seven to ten years in |
| Engagement Manager | pivot | Four to seven years in |
| Associate / Consultant | pivot | Two to four years in |
| Analyst / Business Analyst | entry | Graduate intake |
entry
Analyst / Business Analyst
The first desk: analysis, interviews with client staff, and the slides that carry the answer. Reviewed by every layer above.
Graduate intake, usually converted from a summer internship
pivot
Associate / Consultant
Owns a module of the work and the analysis behind it. The level at which post-MBA and experienced hires usually join.
Promotion after two to four years, or a hire from an MBA or an industry role
pivot
Engagement Manager
Runs the team and the client day to day. The first level at which the work is judged by whether the client acted on it.
Promotion from consultant or associate, typically four to seven years in
senior
Associate Partner / Principal
Shares the client relationship with a partner and starts to sell the next piece of work as well as deliver this one.
Promotion from engagement manager, typically seven to ten years in, or a senior external hire
senior
Consulting Partner
Owns client relationships and the firm’s revenue from them. Paid from the profits of the partnership, not on a salary scale.
Promotion from associate partner, ten to fifteen years in, and for a small fraction of any intake
The career path
Consulting: analyst to partner
Analyst to partner, the two steps that change the job, and why the industry assumes most people leave. How pay is structured, with its one public benchmark named.

Who buys advice, who sells it, and how the money and the people move between them.
2.The firms, by what they sell
Named and grouped, never ranked. The tiers describe different businesses with different work and different lives, and the order carries no meaning.
The three large strategy firms (MBB)
Senior-level strategy advice on short engagements with small teams. The smallest graduate intakes in the industry.
- McKinsey & Company. Entry as a business analyst. Uses a structured personal experience interview alongside the case.
- Boston Consulting Group. Entry as an associate. Recruits office by office.
- Bain & Company. Entry as an associate consultant. Has a large private equity practice alongside its corporate strategy work.
How graduates get in. An internship that converts to a graduate offer, applied for office by office. Bain and BCG both recruit into regional offices with their own windows and, in some markets, their own programme names, so the office’s page is the source and a national deadline may not apply.
Other strategy firms
Global or regional firms that sell strategy and have a clear specialism. Intakes are small to medium and the interview is a case.
- Oliver Wyman. Built on financial services, and part of Marsh McLennan.
- Kearney. Operations and procurement heritage, and formerly A.T. Kearney.
- L.E.K. Consulting. Known for commercial due diligence for private equity buyers, and for growth strategy.
- Roland Berger. Founded in Germany and headquartered in Europe, where its work is concentrated.
How graduates get in. Graduate and internship programmes with their own calendars, usually later than the large three, which makes them a sensible second wave of applications.
The strategy practices of the Big Four
Strategy teams inside the large accounting networks, recruiting separately from the rest of the firm and interviewing in cases.
- Monitor Deloitte. Deloitte’s strategy practice.
- Strategy&. PwC’s strategy consulting business.
- EY-Parthenon. EY’s strategy practice, with a deals and transaction strategy focus.
How graduates get in. Often a distinct graduate or experienced-hire route. Check whether a posting is for the strategy practice or for the wider firm.
The Big Four consulting arms
The consulting businesses of Deloitte, PwC, EY and KPMG. By headcount they are most of the industry, and the work runs from deals and risk to multi-year technology delivery.
- Deloitte. Consulting, deals, risk and technology practices under one graduate programme.
- PwC. Consulting, deals and technology practices, with strategy at Strategy&.
- EY. Consulting and transaction services, with strategy at EY-Parthenon.
- KPMG. Consulting, deals and technology practices.
How graduates get in. Structured graduate schemes in volume, usually opening earlier than the strategy firms, with sponsorship of professional qualifications. The practice you join decides the career far more than the firm.
Technology and implementation firms
Systems, data and transformation delivered by larger teams over longer projects. The largest graduate intakes in the industry.
- Accenture. Technology and operations consulting at very large scale.
- Capgemini. Technology and engineering services, with a consulting arm.
How graduates get in. Graduate schemes in volume, with online assessments and a competency-led interview more often than a case.
Specialists and boutiques
Firms that are deep in one domain: pricing, life sciences, turnaround, the public sector. They hire a handful of graduates each and give depth immediately.
- Simon-Kucher. Pricing and revenue strategy.
- ZS. Life sciences and healthcare commercial strategy.
- Alvarez & Marsal. Turnaround, restructuring and performance improvement.
- FTI Consulting. Restructuring, forensic and economic consulting, and strategic communications.
- Guidehouse. Public sector and regulated industries.
How graduates get in. Direct applications, often with a single intake. Under-applied to, which is the reason to apply.
Economic consultancies
Competition cases, regulatory pricing and damages. A separate profession that hires economists and interviews on economics rather than business cases.
- Compass Lexecon. Competition and regulatory economics.
- Charles River Associates. Economics, finance and management consulting.
- Cornerstone Research. Economic and financial analysis in litigation.
- Analysis Group. Economic, financial and strategy consulting.
- NERA Economic Consulting. Economic analysis for litigation, regulation and policy.
- Oxera. Economic consulting for regulators, utilities and competition cases in Europe.
- Frontier Economics. Economic consulting for competition, regulation and policy.
- RBB Economics. Competition economics.
- Berkeley Research Group. Disputes, investigations and economics.
How graduates get in. Direct from an economics degree or postgraduate study, often with a research assistant or analyst entry.
The list is not exhaustive. The guide to how the firms differ sets out how to choose between them and how to answer why this firm.
Application dates move every cycle and the large firms publish them on their own pages. The opportunity tracker lists programmes that carry an open date and a deadline, and the firm index at Firms A to Z shows what each firm has open.
3.How to prepare, in order
Four stages. The case is a performance skill, so the reading is the smaller half and the practice with a partner is the larger.
Read as a table
| Stage | What it covers |
|---|---|
| Understand the industry | What consultants do, who the firms are and where the ladder goes |
| Get through the door | The calendar, the CV, the online assessments and the shape of the process |
| Learn the case | Structure, case types, market sizing and the arithmetic, each as its own skill |
| Prepare the fit half | The personal experience interview, where one story is probed for twenty minutes |

HireVue Studio
Answer to a camera, on a clock, with no second take, and score yourself against what the round assesses.
For spoken practice, the mock interview asks the case-maths questions and marks the answer against what each one tests.
5.Weighed against the alternatives
The decision is rarely consulting or nothing. These set it beside the three it is most often chosen against.

Questions people ask
What is the difference between MBB and the Big Four?
Scale and product. The three large strategy firms hire in small numbers to sell senior-level advice on short engagements. The consulting arms of the Big Four hire in volume across everything from strategy and deals to multi-year technology delivery, so the practice you join matters far more than the firm name.
How long does it take to prepare for a case interview?
Six to eight weeks of real work is the usual figure, most of it live practice with a partner. Twenty to thirty cases is enough to become comfortable. Market sizing and mental arithmetic need their own daily drills, because they fail independently of case structure.
Do I need a business degree for consulting?
No. Firms hire humanities students, scientists, engineers, lawyers and career changers. The screen looks for analytical capability, achievement and enough polish that a client would take you seriously, and any subject can provide that evidence.
How does consulting compare with banking for a graduate?
Hours are lower and differently shaped, entry pay is close and usually slightly below banking once the bonus is counted, and the work is broader and shallower. Consulting teaches problem structuring across industries and banking teaches transactions and modelling in depth. Both feed private equity and corporate strategy, by different doors.
What is up-or-out?
The convention that not being promoted within a window means leaving. In practice most firms handle it as a supported transition over months. The pyramid narrows sharply, so planning on two to four years as a valuable and finite investment is the sound assumption.
