McKinsey Operations Practice: Careers and Interview (2026)
Author: Taylor Warfield, Former Bain Manager and interviewer
Last Updated: June 4, 2026
The McKinsey Operations Practice is the firm's largest functional group, focused on helping clients improve how they make, move, and deliver their products and services. It covers manufacturing, supply chain, procurement, product development, capital projects, and service operations. According to McKinsey, roughly one in three of the firm's projects now involves an operations topic.
As a former Bain Manager and interviewer, I have helped thousands of candidates target functional practices like this one. By the end of this article, you will know what the practice does, how operations consultants differ from generalists, what the OEP is, and how to land an offer.
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 Is the McKinsey Operations Practice?
The McKinsey Operations Practice is the part of the firm that helps clients run their core business processes better. It is the firm's largest functional practice and, by McKinsey's own description, the largest organization of its kind in the world. Operations work spans the full value chain, from how a product is designed to how it reaches the customer.
Most people picture McKinsey as a pure strategy shop. The reality is that a large share of the firm's work is operational, helping clients cut costs, raise productivity, and fix broken processes. Operations is where boardroom strategy meets the factory floor.
What Does the McKinsey Operations Practice Do?
The practice helps clients improve performance across six core areas: manufacturing, supply chain, procurement, product development, capital projects, and service operations. The goal is almost always the same, which is higher productivity, lower cost, and better quality. Work runs from early diagnosis all the way through to implementing changes on the ground.
What Are the Main Service Lines?
The Operations Practice is organized around a handful of capability areas, each pointed at a different part of the value chain. The table below shows what each one focuses on.
Service line |
What it focuses on |
Manufacturing and supply chain |
Plant productivity, lean operations, network design, inventory, and logistics |
Product development and procurement |
Design-to-value, sourcing strategy, and supplier negotiations |
Capital excellence |
Large capital projects, infrastructure, and capital productivity |
Service operations |
Back-office, customer service, call centers, and shared services efficiency |
A key point most candidates miss is that the practice does not stop at recommendations. Operations teams often stay on site to implement changes, measure results, and build the client's own capabilities. That hands-on, results-driven work is what separates operations from pure strategy.
How Is an Operations Consultant Different From a Generalist?
An operations consultant joins McKinsey with a specialization in operations, while a generalist works across all problem types and industries. Operations consultants are staffed onto projects that need their functional expertise, and they often sit on the same teams as generalists. Generalists tend to serve clients near their home office, while operations consultants are deployed globally based on where their skills are needed.

According to McKinsey's own careers page, operations consultants work on teams together with generalists to solve complex strategic and operational problems, from early issue diagnosis to implementing the final recommendations. In practice this means you get the McKinsey brand and pay, plus a clear functional identity. The trade-off is that you commit to operations earlier than a generalist would.
What Is the Operations Excellence Program (OEP)?
The Operations Excellence Program (OEP) is McKinsey's early-tenure program for building operations expertise. It develops specialized skills through apprenticeship and hands-on training in one of four capability areas. More than 600 consultants have started their McKinsey careers through the OEP.
The OEP is built around four capability tracks:
- Manufacturing and supply chain
- Product development and procurement
- Capital excellence
- Service operations
The program combines three things: extensive networking, focused apprenticeship at client sites, and structured training. McKinsey treats network building as one of the biggest success factors in the program. The OEP has also won a Brandon Hall Group gold award for excellence in learning.
Who Does the McKinsey Operations Practice Hire?
McKinsey hires operations talent at two main entry points: early-career candidates joining through the OEP and experienced professionals joining as operations specialists. The strongest candidates usually have a background in engineering, manufacturing, supply chain, procurement, or another technical field. Lean, Six Sigma, or continuous improvement experience is a real advantage.
Degrees range from bachelor's and master's to MBA and PhD, often with an engineering or business focus. Experienced hires typically bring two to ten years of functional experience in areas like operational excellence, sourcing, or project management. These hires usually go through the McKinsey specialist interview, which adds an expertise component on top of the standard rounds.
How Do You Get a Job in the McKinsey Operations Practice?
Getting into the McKinsey Operations Practice follows the same core path as any McKinsey role: application, the Solve assessment, and one or two rounds of interviews. Each round pairs a case interview with a behavioral interview called the PEI. Operations and specialist candidates may also face an expertise interview that tests functional depth.
What Does the Interview Process Look Like?
The process has four main stages. Each one screens out a large share of candidates, so you need to prepare for all of them.
- Application. You submit a resume, an optional cover letter, and basic details like office and language preferences.
- Online assessment. Most candidates take the McKinsey Solve game, a gamified assessment with two modules called Redrock Study and Sea Wolf. Only about 20% of candidates pass.
- First round interviews. Usually two interviews, each combining a case and a behavioral portion.
- Final round interviews. Two or three interviews, sometimes including an expertise interview for operations specialists.
The behavioral portion is the McKinsey PEI, which tests four traits: Connection, Drive, Leadership, and Growth. The PEI counts for roughly half of your overall assessment, so it is not something to wing. Prepare at least two detailed stories for each trait.

What Does an Operations Case Interview Look Like?
An operations case interview at McKinsey is usually a standard case with an operational twist rather than a deeply technical exam. Many take the form of a profitability or process case where the real driver is something operational like capacity, throughput, or inventory. Interviewers want structured thinking, clean math, and practical business sense, not memorized lean jargon.
The most common version asks you to find and fix a bottleneck in a process. Supply chain cases are also frequent, so practicing a few supply chain case examples pays off. The McKinsey case interview is interviewer-led, meaning the interviewer guides you through a structured set of questions.
Here's an example. A factory runs four production steps, and one step can only handle 80 units an hour while the others handle 120. That slow step is the bottleneck, so total output is capped at 80 units an hour no matter how fast the rest move.
A strong candidate maps the process, finds the constraint, then brainstorms ways to lift it before touching the math.
Operations cases reward strong fundamentals over fancy theory. If you want to learn case interviews quickly, my case interview course walks you through proven strategies in as little as 7 days.
How Much Do McKinsey Operations Consultants Make?
McKinsey operations consultants are paid on the same scale as generalist consultants at the same level. Based on 2026 Glassdoor and industry data, a US Business Analyst earns a base salary of roughly $112,000, and a post-MBA Associate earns a base of around $192,000. Total compensation jumps sharply at the Associate Partner level and above, where profit sharing kicks in.
Entry point |
Typical US base salary (2026) |
Business Analyst (undergrad or non-MBA master's) |
About $112,000 |
Associate (post-MBA or PhD) |
About $192,000 |
Work-life balance and pay are broadly the same as the generalist track. The main difference is that you specialize earlier and may spend more time at client sites. The McKinsey career path runs from Business Analyst to Senior Partner, and operations consultants move through the same levels.
What Are the Pros and Cons of the McKinsey Operations Practice?
The Operations Practice offers the same brand, pay, and prestige as the generalist track, plus a clear functional identity. The main downside is that you commit to operations earlier, which narrows your exposure to other problem types. The table below sums up the trade-offs.
The main advantages are:
- Same pay and McKinsey brand as the generalist track
- Deep, marketable expertise in a high-demand area
- Strong exit options into industry operations and COO roles
- Hands-on impact you can see and measure at client sites
The main drawbacks are:
- You specialize early, which limits breadth across problem types
- More time on site at factories, plants, and warehouses
- More travel than some office-based generalist projects
- Deep expertise can pigeonhole you if your interests later shift
How Can You Stand Out in McKinsey Operations Recruiting?
There are five things that consistently set strong operations candidates apart. Work through each one before you apply.
Tip #1: Lead With Real Operations Experience
McKinsey hires operations talent for functional depth, so put your operations work front and center. Highlight projects involving manufacturing, supply chain, sourcing, lean, or Six Sigma. Quantify the impact, such as cutting cycle time by 30% or reducing inventory by $2 million.
Tip #2: Master the Fundamentals Before the Jargon
Interviewers care more about clear thinking than buzzwords. Make sure you can run a clean profitability and process case before you worry about advanced operations theory. The quickest way to fail is to lean on memorized frameworks instead of structuring the actual problem in front of you.
Tip #3: Practice Process and Capacity Cases
Operations cases often hinge on finding a bottleneck or sizing capacity. Practice mapping a process into clear steps, then identifying the constraint. Keep your math simple and use round numbers so you can move fast and avoid errors.
Tip #4: Prepare Your PEI Stories Seriously
The PEI counts for roughly half your assessment, yet many strong case solvers neglect it. Prepare two detailed stories for each of the four traits, with specific actions and measurable results. Practice telling them out loud until they feel natural, not scripted.
Tip #5: Network With Operations Consultants
Generic networking helps, but talking to actual operations consultants helps more. They can tell you what the day-to-day looks like, refer you, and prep you for the expertise interview. Reach out through LinkedIn, alumni networks, and McKinsey recruiting events.
Frequently Asked Questions
Is the McKinsey Operations Practice prestigious?
Yes. It is McKinsey's largest functional practice and carries the same brand, pay, and prestige as the generalist track. The work is widely respected because operations consultants sit on the same client teams and deliver measurable, hands-on results.
Do McKinsey operations consultants get paid less than generalists?
No. Operations consultants are paid on the same salary scale as generalists at the same level. In 2026, that means a base of about $112,000 for a Business Analyst and about $192,000 for a post-MBA Associate, rising with each promotion.
Can you switch from operations to generalist at McKinsey?
Movement is possible but not automatic. Operations consultants already work alongside generalists on mixed teams, so some people shift toward more generalist work over time while others go deeper into their specialty. Talk to a recruiter about how flexible your specific office is.
Do you need an engineering degree to join the Operations Practice?
No, but a technical background helps. Many operations consultants hold engineering or science degrees, yet McKinsey also hires from business, supply chain, and operations management. What matters most is demonstrated functional expertise, strong problem solving, and ideally some lean or Six Sigma experience.
Is the operations case interview harder than a normal case?
Not harder, just slightly different in flavor. Operations cases are usually standard cases with an operational angle, such as a process or capacity problem, and they test the same skills as any McKinsey case. You rarely need deep technical knowledge to solve them.
What is the difference between the OEP and a normal McKinsey role?
The Operations Excellence Program is an early-tenure track focused on building deep operations skills through apprenticeship and training. A normal generalist role rotates across many problem types and industries. OEP consultants specialize from the start in one of four capability areas, while generalists specialize much later.
What exit opportunities do McKinsey operations consultants have?
Operations consultants have strong exits into industry operations roles, supply chain leadership, and COO tracks. Private equity operating roles and corporate strategy are also common destinations. The hands-on, results-focused nature of the work plus the McKinsey brand makes the experience highly transferable across industries.
