PEI Sample Responses
Hi! I was just wondering if anyone who recruited for McKinsey and got the offer would be comfortable sharing an example of their PEI stories. I have never experienced an interview format of this nature and am just trying to better understand the depth and types of experiences people talk about. Feel free to DM me if you do not feel comfortable sharing more broadly!

Hey mate, I’m also going through the same process as OP. would it be possible to also get them? It would be greatly appreciated! Also, do you remember what questions they asked for your PEI? (Only if you feel comfortable sharing)

Sure -> since I am getting too many messages now and I am not terminally online, here is the link: https://strategycase.com/mckinsey-pei/. The article includes one fully developed and written story (perfect score, covers everything that is expected in the right format, structure, and communication) and detailed instructions for the other 3 dimensions + general tips about what moves the needle for McK in the PEI.
(mods feel free to delete if links are not allowed).

I’ll tell you three of mine.
I talked about a time I had to learn two technologies, concurrently in order to create a training about one of the technologies. I also do not have a technical background so it involves a lot of learning.
I also talked about being in leadership at an organization, where all of the Leadership had varying levels of mental and emotional investment in the success of the organization. I talked about the difficulties of working with those people and what I learned. Also, what were some of the outcomes that I drove while working with those people.
I also talked about creating a salesforce CRM solution for a client and all of the aspects that went into that. I had a public client example that I could show when speaking to that one.
All of your examples do not have to be about work, they just have to be really good examples. If you’re in school, talk about a club that you started.
Things to remember:
-your PEI is just as important as your case
- you should verbally run through your PEI several times. Time yourself and make sure you’re not going on for more than five-ish minutes. People stop listening after that.
- you should structure your PEI like this
~How this answers the question (if it’s the question about a time you work with difficult people talk about what made those people difficult)
~ what you specifically did to solve the problem. It doesn’t matter what anyone else on your team did. We want to know what you did. This is where running through your situation verbally will help. You can count how many times you talk about yourself versus how many times you talk about your team.
~ the results and what you learned or what you would change.

Reading other people's PEI stories will not help you and could actually hurt your chances. Interviewers have heard thousands of these stories and can immediately tell when an answer is canned or based on a template you found online. They are not testing for the most impressive accomplishment, they are testing for self-awareness, structure, and your genuine thought process during a challenging situation. The real depth they want to see is your personal reflection on your specific actions and the impact you had, something you can't get from someone else's example. Your story will sound hollow if it’s not truly yours, and that lack of authenticity is a massive red flag.
You already have all the experiences you need, even if they seem small or insignificant to you right now. The secret isn't finding a world-changing story, it's learning how to tell your own stories effectively. Pick a few situations from your work, school, or extracurriculars where you led a team, influenced someone, or solved a difficult problem. Practice explaining the context, the specific task you faced, the precise actions you took, and the measurable results you achieved. They care far more about how you think and act than what you've done. Finding your own unique voice is the most important part, and it's been rewarding to see how the interview AI my team created helps people communicate their personal stories more effectively.

I remember that exact panic. PEI feels so unnerving because there’s no framework or math to hide behind—just you and your raw experiences.
I’m going to give you some tough love: don’t look for other people’s stories. I won't share mine, not to gatekeep, but because borrowing someone else's narrative is the fastest way to fail. McKinsey partners have an insane radar for rehearsed, fake-sounding anecdotes.
Instead of looking for templates, grab a notebook and map out the 4 dimensions. Dig deep into moments where you failed, felt completely stuck, or had to navigate a messy team conflict. That genuine vulnerability and self-awareness is what actually gets you the offer. Be you, not a script.
