McKinsey PEI (Personal Experience Interview) is a structured behavioral interview that takes up 10 to 20 minutes of every McKinsey interview. McKinsey updated the PEI dimensions in mid-2025, and interviewers now assess four traits: Connection, Drive, Leadership, and Growth.

 

In this article, you will learn exactly what each dimension means, see 30+ real PEI questions reported by candidates, get two full example answers using the SPAR framework, and follow a 6-step preparation plan that has helped hundreds of candidates pass the McKinsey PEI.

 

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 Changed in 2026?

 

McKinsey renamed and reorganized its PEI dimensions in summer 2025. The substance of the interview did not change dramatically, but the labels are new and important to know.

 

The old framework listed six qualities: personal impact, entrepreneurial drive, inclusive leadership, courageous change, problem solving, and expertise. The updated framework focuses the PEI on four dimensions. Problem solving is now assessed exclusively through the case interview.

 

Old Name	New Name	What It Tests
Personal Impact	Connection	Influencing and persuading others
Entrepreneurial Drive	Drive	Resilience and resourcefulness
Inclusive Leadership	Leadership	Leading diverse teams to results
Courageous Change	Growth	Adapting to change and feedback

 

According to McKinsey's careers page, candidates should prepare two personal examples for each of these four dimensions. That means you need at least eight stories ready before interview day.

 

What Is the McKinsey PEI?

 

The McKinsey PEI is a behavioral interview where you discuss one personal experience in depth for 10 to 20 minutes. Unlike traditional behavioral interviews that cover many questions quickly, the PEI zeroes in on a single story and probes it with 10 to 25 follow-up questions.

 

The interviewer is not just listening to what you did. They want to understand why you made each decision, how you felt at key moments, what you would do differently, and what you learned. In my experience coaching hundreds of candidates, the depth of probing is what catches people off guard.

 

The PEI shares some similarities with consulting behavioral and fit interview questions. Both formats ask you to draw on past experiences. The key difference is that the McKinsey PEI goes much deeper on a single story rather than covering multiple stories at a surface level.

 

How Is the PEI Different from Traditional Behavioral Interviews?

 

The table below highlights the main differences. Understanding these will help you calibrate how much detail to prepare for each story.

 

Factor	McKinsey PEI	Standard Behavioral
Duration	10-20 minutes	3-5 minutes
Stories per interview	1 story, explored deeply	3-5 stories, surface level
Follow-up questions	10-25 probing questions	1-2 clarifying questions
Focus	Why you did it, how you thought	What you did, what happened
Traits assessed	4 specific dimensions	Varies by firm
Used by	McKinsey only	BCG, Bain, Deloitte, others

 

When Is the McKinsey PEI Given?

 

The PEI is given in every McKinsey interview, either at the start or end of the session. Each interview typically lasts 45 to 60 minutes, with the PEI taking up roughly one third of that time and the case interview filling the rest.

 

Your McKinsey first round interview usually has two back-to-back interviews, and your McKinsey final round interview has two to three. That means you will answer the PEI four to five times total across both rounds.

 

Since each PEI lasts 10 to 20 minutes, you will spend 40 to 100 minutes in total on PEI questions. That is more time than most candidates spend preparing for them, which is a huge mistake.

 

What Are the 4 McKinsey PEI Dimensions?

 

McKinsey publicly lists the four PEI dimensions on their careers page. Each interviewer will focus on one dimension and probe it deeply. In the first round, interviewers typically focus on Leadership and Connection. In the final round, all four dimensions are assessed.

 

What Is Connection (Personal Impact)?

 

Connection tests your ability to influence, persuade, and build trust with other people, especially when they disagree with you. McKinsey consultants regularly need to convince senior executives to take difficult actions, often without any formal authority.

 

Your story should demonstrate empathy, strong communication, and the ability to navigate conflict or resistance. The best stories show that you understood the other person's perspective before trying to change it.

 

What Is Drive (Entrepreneurial Drive)?

 

Drive tests your resilience, resourcefulness, and willingness to push through obstacles. This is not about being an entrepreneur. It is about showing an entrepreneurial mindset when facing tough situations.

 

The best Drive stories involve a challenge where you took ownership, created a plan, and executed it relentlessly. McKinsey wants to see that you do not freeze when things get hard. According to Glassdoor data, roughly 30% of PEI questions fall into this category.

 

What Is Leadership (Inclusive Leadership)?

 

Leadership tests your ability to lead a team of diverse people toward a common goal. The "inclusive" part matters. McKinsey wants to see that you can bring out the best in people with different backgrounds, skill levels, and perspectives.

 

You do not need to have held an official leadership title. If you led without being the designated leader, that is actually a stronger example. The story should show how you structured work, motivated team members, and drove results.

 

What Is Growth (Courageous Change)?

 

Growth is the newest PEI dimension. It tests your ability to adapt when circumstances change unexpectedly and to receive feedback with a positive, growth-oriented mindset.

 

McKinsey consultants receive manager feedback every one to two weeks and switch projects frequently. Each new project is essentially a new job with a new team. Your story should show that you handled ambiguity or disruption with courage rather than resistance.

 

What McKinsey PEI Questions Will You Be Asked?

 

The PEI is highly predictable. McKinsey tells candidates which dimensions to prepare for, and the opening questions almost always follow a standard format. Below are 30+ real questions reported on Glassdoor and by candidates I have coached, organized by dimension.

 

Connection (Personal Impact) Questions

 

• Tell me about a time you had to convince someone to change their mind.

 

• Describe a situation where you disagreed with a teammate and how you resolved it.

 

• Give me an example of a time you persuaded a group to take a different approach.

 

• Tell me about a time you had to resolve a conflict in a team setting.

 

• Describe a time you had to influence someone without having authority over them.

 

• Tell me about a challenging situation when you worked with someone who had an opposing opinion.

 

• Give an example of a time you got buy-in from a reluctant stakeholder.

• Describe how you handle delegating work across a team with varying skill levels.

 

• Tell me about a time you influenced someone without having formal authority.

 

• Give me an example of a time you went above and beyond what was expected.

 

Growth (Courageous Change) Questions

 

• Revisit a time when you experienced a significant change and share how you adapted.

 

• Tell me about a time you received tough feedback and what you did with it.

 

• Describe a situation where the plan changed and you had to adjust quickly.

 

• Tell me about a time you had to learn something new under pressure.

 

• Describe a time when you embraced a change others resisted.

 

• Tell me about a setback that taught you something important.

 

• Give an example of a time when ambiguity forced you to think on your feet.

 

How Should You Structure Your McKinsey PEI Answer?

 

Structure is one of the most important qualities in consulting, and your PEI answer should reflect that. I recommend the SPAR framework: Summary, Problem, Action, Result. This is a slightly adapted version of the classic STAR method that makes your answer more concise and easier to follow.

 

Summary (10-15 seconds)

 

Give a one-sentence preview of your story. This tells the interviewer the "what" so they can focus on the "how" for the rest of your answer. For example: "I am going to share how I helped save my company $10M per year by analyzing customer data and collaborating with cross-functional teams."

 

Problem (30-45 seconds)

 

Briefly describe the situation and the challenge you faced. Keep this short. Spending too much time on context is one of the most common PEI mistakes. Aim for three to four sentences covering what you were asked to do, why it mattered, and what made it difficult.

 

Action (2-3 minutes)

 

This is the most important section. Explain the specific steps you took. Use "I" instead of "we" to emphasize your personal contribution. Cover what you did, how you did it, and why you chose that approach. The interviewer will likely interrupt this section with follow-up questions, so know every detail.

 

Result (30-45 seconds)

 

Quantify your impact wherever possible. Did revenue increase? Did you save money? Did you hit a deadline that seemed impossible? Also share what you learned from the experience and how it changed you. Reflection is a key part of what McKinsey evaluates.

 

Your initial answer should only last about 3 to 4 minutes. The remaining 7 to 15 minutes will be filled with follow-up questions from the interviewer. Do not try to deliver a 10-minute monologue.

 

If you want a structured way to craft your SPAR stories with templates and sentence-by-sentence guidance, my fit interview course walks you through the entire process in about 3 hours.

 

What Does a Strong McKinsey PEI Answer Look Like?

 

Below are two full example answers using the SPAR framework. These show the initial answer you would give before the interviewer begins probing with follow-up questions.

 

Example 1: Tell Me About a Time You Went Above and Beyond

 

Summary: "I am going to share how I helped Apple increase revenues by $100M by taking on a data project outside of my job responsibilities."

 

Problem: "While working at Apple in the AppleCare business, I was responsible for analyzing customer satisfaction data. I noticed an opportunity to use purchasing data to predict which customers were likely to cancel their AppleCare subscriptions. This was outside my job description, but I believed it could have a major revenue impact."

 

Action: "I pulled over five years of purchasing data for 10 million customers and built a logistic regression model to identify at-risk subscribers. I verified the model with data scientists and got buy-in from the AppleCare strategy team. I proposed that Apple send targeted discount codes to the top 10% of customers most likely to cancel."

 

Result: "My analysis showed Apple could increase revenues by $100M annually. I presented the findings to the head of AppleCare, who approved testing the campaign in several cities. I learned how to build credibility and get stakeholder buy-in for ideas that nobody asked me to pursue."

 

Example 2: Tell Me About a Time You Had to Motivate Someone

 

Summary: "I am going to share how I turned around an underperforming team member at Amazon by diagnosing the root cause and providing hands-on support."

 

Problem: "I led a four-person analytics team at Amazon working on a customer service improvement project. After a few weeks, one member, John, was consistently delivering late, low-quality work. Three other members were performing well, so I suspected this was an individual motivation issue."

 

Action: "I sat down with John one-on-one to understand the root cause. The problem was that our team had recently switched to Tableau, and John found it difficult to set up. He was unmotivated to switch from Excel, which he was an expert at. I set up three training sessions to walk him through Tableau's setup and showed him how it could save him time on computationally intensive tasks."

 

Result: "John became excited about Tableau and began consistently delivering high-quality work on time. He even started exploring additional features for other projects. I learned that performance issues are often skill gaps in disguise, and that investing time in one-on-one coaching can transform outcomes quickly."

 

What Follow-Up Questions Will the Interviewer Ask?

 

This section is critical. Having coached hundreds of McKinsey candidates, I can tell you that the follow-up questions are where most people stumble. The interviewer will interrupt your story and drill into specific moments. Here are the most common probes:

 

• Why did you decide to take that specific approach?

 

• What other options did you consider, and why did you reject them?

 

• How did the other person or team react to your actions?

 

• What was going through your mind at that moment?

 

• What would you do differently if you could go back?

 

• How did you know your approach was working?

 

• What data or evidence did you use to make that decision?

 

• How did you handle the pushback you received?

 

• What did you learn about yourself from this experience?

 

• How has this experience changed the way you approach similar situations?

 

The key to handling these questions is preparation. If you have lived through the experience and reviewed every detail in advance, you will answer confidently. If you have to make things up on the spot, the interviewer will notice immediately.

 

How Do You Prepare for the McKinsey PEI?

 

Preparation is the single biggest predictor of PEI success. Based on Glassdoor interview reviews, candidates who spend at least 5 to 10 hours on PEI prep pass at roughly double the rate of those who wing it. Here is a 6-step plan:

 

Step 1: Select 8 to 10 stories.

 

Draw from your professional, academic, and extracurricular experiences. Pick stories that are impressive, specific, and ideally from the last 2 to 3 years. McKinsey's careers page recommends preparing two examples per dimension, which means at least eight stories total.

 

Step 2: Map each story to a PEI dimension.

 

Make sure you have at least two stories for each of the four dimensions: Connection, Drive, Leadership, and Growth. Some stories can flex across dimensions, but have a primary mapping for each.

 

Step 3: Write out every detail.

 

For each story, write down every detail you can remember. Who was involved? What specific actions did you take? How did other people react? What data did you use? What was the quantified result? The more detail you have prepared, the better you will handle follow-up questions.

 

Step 4: Structure each story using SPAR.

 

Write out the Summary, Problem, Action, and Result for each story. Time yourself delivering it. Your initial answer should be 3 to 4 minutes, not longer.

 

Step 5: Practice out loud with a partner.

 

Practice telling your stories to another person and have them ask unexpected follow-up questions. Practice until you can tell each story confidently without sounding rehearsed or robotic. If you want expert feedback, my 1-on-1 coaching helps you improve roughly 5x faster than solo practice.

 

Step 6: Prepare for interview day logistics.

 

Do not repeat the same story to different interviewers in the same round. Interviewers compare notes afterward. You can reuse stories across rounds (for example, telling a first-round story again in the final round), but never within the same round.

 

What Are the Biggest McKinsey PEI Mistakes?

 

After coaching candidates through over 500 mock PEI sessions, I see the same mistakes again and again. Avoiding these will put you ahead of most applicants.

 

1. Spending too long on the setup.

 

Candidates often spend 3 to 4 minutes just describing the context and only 1 minute on their actions. Flip this. Keep the setup to 30 to 45 seconds and spend most of your time on what you did and why.

 

2. Saying "we" instead of "I."

 

The PEI is about your individual contribution. When you say "we decided" or "our team built," the interviewer cannot tell what you specifically did. Use "I" consistently.

 

3. Picking a story that does not match the dimension.

 

If the interviewer asks about a time you influenced someone (Connection), do not tell a story about solo problem solving. Interviewers will sometimes stop you and ask for a different story, which wastes time and shakes your confidence.

 

4. Not knowing the details of your own story.

 

McKinsey interviewers ask 10 to 25 follow-up questions. If you cannot remember what happened at a specific moment, you will either freeze or make something up. Both are immediately obvious to a trained interviewer.

 

5. Repeating stories in the same round.

 

Each interviewer expects a unique story. Reusing a story makes it look like you have a thin track record of accomplishments. Prepare at least 8 stories so you always have fresh material.

 

6. Forgetting to quantify results.

 

Vague outcomes like "it went well" or "the client was happy" do not give the interviewer anything concrete to evaluate. Wherever possible, use specific numbers: revenue impact, time saved, percentage improvement, or team size managed.

 

7. Not practicing enough.

 

Most candidates spend hundreds of hours on case prep and less than one hour on the PEI. Yet the PEI carries equal weight to the case interview. Even 5 hours of focused PEI practice can give you a significant edge.

 

How Is the McKinsey PEI Scored?

 

McKinsey does not publish an official scoring rubric, but based on what former interviewers have shared, candidates are evaluated on four criteria during each PEI session.

 

Criteria	What the Interviewer Evaluates
Trait alignment	Does the story clearly demonstrate the dimension being tested?
Depth and clarity	Can you explain your decisions and reasoning in specific, convincing detail?
Impact	Did your actions lead to a measurable, meaningful outcome?
Self-awareness	Do you show genuine reflection on what you learned and how you grew?

 

A weak PEI can sink an otherwise strong candidacy. According to former McKinsey interviewers, the PEI carries roughly equal weight to the case interview in the final hiring decision. You cannot pass on case performance alone.

 

If you are struggling to craft answers that hit all four criteria, my fit interview course gives you fill-in-the-blank templates and rubrics that show you exactly what interviewers are looking for.

 

Frequently Asked Questions

 

How Many Stories Should I Prepare for the McKinsey PEI?

 

Prepare at least 8 stories, two per dimension (Connection, Drive, Leadership, Growth). Having 8 to 10 stories gives you flexibility to pick the best fit for each question and ensures you never repeat a story within the same interview round.

 

Can I Use the Same Story for Different PEI Dimensions?

 

Yes, but you need to reframe the emphasis. A story about leading a team through a crisis could work for Leadership or Drive depending on which aspect you highlight. However, you should never use the same story with two different interviewers in the same round.

 

Do My PEI Stories Need to Be from Work Experience?

 

No. McKinsey accepts stories from professional work, university, volunteer activities, sports teams, and personal projects. The key is that the story demonstrates the relevant trait with specific actions and measurable impact. Stories from the last 2 to 3 years tend to work best because you can remember details more clearly.

 

How Long Should My Initial PEI Answer Be?

 

Your initial SPAR answer should be about 3 to 4 minutes. The remaining 7 to 15 minutes will be filled with interviewer follow-up questions. Delivering a 10-minute monologue is a common mistake that signals you cannot communicate concisely.

 

What If the Interviewer Asks Me to Pick a Different Story?

 

This happens occasionally and is not a bad sign. The interviewer may want to explore a different dimension or may have already heard your first story summarized in another interviewer's notes. Simply pivot to another prepared story. This is why preparing 8 to 10 stories is so important.

 

Is the McKinsey PEI a Culture Fit Interview?

 

No. McKinsey's Global Director of Talent Assessment has publicly stated that the PEI is not a fit interview. Unlike culture fit assessments, the PEI is standardized to reduce bias. Every candidate gets the same type of prompts, and interviewers are trained to assess specific, predefined traits rather than personal rapport.

 

What Happens If I Fail the PEI but Ace the Case?

 

A weak PEI can cost you the offer even if your case performance is excellent. The PEI and case interview carry roughly equal weight in McKinsey's hiring decision. Many rejections come from the PEI, not the case, which is why preparation is so important.
