The Most Prestigious Career Is Eating Itself

For decades, the management consulting interview was a rite of passage for the ambitious. You learned to crack cases, estimate the number of ping pong balls that fit in a Boeing 747, and speak fluently about synergies you had never witnessed. If you survived, you joined a firm where you would spend two to four years working 70-hour weeks, flying business class to cities you never saw, and producing slide decks that told senior executives things their own employees had been trying to tell them for years. Then you left, as almost everyone does, with a credential that opened every door in the corporate world. Management consulting was, for thirty years, the most reliable career escalator in professional services. That escalator is slowing down, and AI is the primary reason why.
McKinsey’s revenue has hovered around $15 billion to $16 billion for the past five years, according to Bloomberg, after a decade of rapid expansion that saw its employee count climb from 17,000 in 2012 to 45,000 by 2022. Headcount has since slid to approximately 40,000. In December 2025, Bloomberg reported that the firm was planning further cuts of up to 10 percent in some non-client-facing areas over the next 18 to 24 months. McKinsey, Deloitte, KPMG, EY, and PricewaterhouseCoopers have all announced waves of layoffs since 2023. The management consulting industry, which spent thirty years telling other companies how to restructure themselves, is now restructuring.
What Management Consulting Sells
The product was never the slide deck. Management consulting sold three things: access to proprietary frameworks built from thousands of engagements, a credible outside voice that gave internal recommendations political cover, and a pipeline of extremely capable young analysts who would work brutal hours at a rate that was still cheaper than hiring the equivalent talent full-time.
The first two remain defensible. A firm like McKinsey still carries relationships, brand, and pattern recognition across industries that no AI model replicates on its own. The third is disappearing fast.
McKinsey’s global managing partner Bob Sternfels signalled the direction in late 2025, telling staff the firm would “probably have fewer folks in the non-client-deployed areas.” James O’Dowd, founder and CEO of professional services placement firm Patrick Morgan, was more direct in a LinkedIn post, estimating McKinsey’s headcount was already down 25 percent from peak levels. “The uncomfortable reality,” O’Dowd wrote, “is that demand for traditional strategy consulting is structurally declining.”
The tasks that junior consultants spent most of their time on, gathering market data, building financial models, synthesising research into readable summaries, drafting the first version of a client presentation, are precisely the tasks that AI handles fastest and best. McKinsey has deployed its own internal AI tool, Lilli, which synthesises over 100,000 proprietary documents and interviews. BCG rolled out ChatGPT Enterprise to its entire 33,000-person workforce in 2023 and has since had employees build over 18,000 custom AI tools for internal use. BCG’s AI work now contributes 20 percent of its total revenue. The firms are not ignoring AI. They are using it to do what junior consultants used to do, and then employing fewer junior consultants.
Revenue Flat, Headcount Falling, Pyramid Inverting
McKinsey’s revenue has held roughly flat at $15 billion to $16 billion for five consecutive years while its workforce shrank from 45,000 to around 40,000. That combination, stable revenue and a smaller workforce, sounds like improving efficiency. What it actually describes is a firm where the analytical work that used to require armies of junior staff is being automated, and where the partners at the top are billing the same amount with fewer people below them. The pyramid model that management consulting has run on since the 1960s is not collapsing. It is inverting.
AI is not the only pressure. Saudi Arabia, which had been paying McKinsey at least $500 million annually in the decade leading up to 2024, according to Bloomberg, cut those payments sharply as the government pared its spending on outside advisors. Political pressure in the United States over McKinsey’s work with government-linked clients in China led to 500 job cuts in the firm’s Greater China unit in 2024. A $641 million settlement over its advisory role for opioid manufacturers cost the firm both money and client confidence. These are reputational and geopolitical problems, not AI problems. But they are compressing revenue at precisely the moment when the core analytical product that justified the headcount is being automated away.
The Talent Is Already Leaving
Management Consulted, a research firm that tracks MBB career patterns, published its Exit Opportunity Analysis in December 2025. The findings describe what has been obvious to anyone watching the industry: consultants are leaving faster and earlier than they used to, and they are going to private companies, VC-backed startups, and AI firms rather than the corporate roles that used to absorb them.
The ex-consultant founder is becoming a recognisable archetype. Arda Ecevit, who spent years at Bain and Deloitte before founding AI strategy startup Nexstrat.ai in 2024, told Business Insider that his platform mirrors the hypothesis-based problem solving used by consulting firms, with multiple AI agents fulfilling the roles of project manager, chief strategy officer, and AI advisor. Alibek Dostiyarov, a former McKinsey consultant, cofounded Perceptis, an AI platform that automates the proposal writing and business development work that smaller consulting firms typically do manually. Bloomberg reported in October 2025 that ex-McKinsey consultants were actively training the AI models designed to automate what they used to do themselves.
Management consulting built its franchise partly on advising clients about workforce transformation and the future of work. The firms are now the subject of exactly the analysis they used to sell.
What Management Consulting Becomes
The management consulting firms that are growing are the ones furthest from the pure strategy model. Accenture, built around implementation rather than advice, hired over 77,000 AI and data professionals in 2025 despite its own rounds of layoffs. Accenture secured $3.6 billion in generative AI bookings in 2024. Deloitte’s AI-related revenue was up 30 percent in its 2025 financial year. The execution-centric firms, which were always considered less prestigious than the pure strategy houses, are outgrowing them.
Fast Company reported in December 2025 that the value in management consulting is moving away from the analysis and synthesis that AI now handles and toward large-scale change management, implementation, and the kind of senior judgment that does not compress into a prompt. Jeffrey Saviano, who spent 30 years at Ernst and Young and co-authored a Harvard Business Review piece on the consulting transition, put it plainly in a LinkedIn post: “The winners won’t be those who merely bolt AI onto an old pyramid. They will be those who reimagine the model entirely: leaner, more expert-driven, and governed with responsibility.”
That is a description of a smaller, more expensive, more selective industry. The graduate intake that made management consulting the dominant post-MBA destination for three decades will shrink. The firms will survive. The career path, as it has existed, will not survive in its current form.
The talent that once flowed into McKinsey and BCG has to go somewhere. Some is going to the AI startups that are automating what analysts used to do. Some is going into the corporate roles that consulting used to prepare people for, only earlier. Others are founding the boutique AI-native firms that are already competing with the legacy houses on price and speed, if not yet on brand. The pyramid is not collapsing. It is just getting much shorter at the bottom, and the people who used to fill those lower floors are building different buildings entirely.
