Value & Purpose Interview at McKinsey

Hi,

To answer your question - feel free to stick to the stories you have already prepared well, no need for an overkill here!
 
Speaking from experience, back when I interviewed with the Firm, I only had three well thought-through stories for all my 7 interviews in total, so less can be more as well! :) (Repetition across rounds isn't a big deal!)

Are you perhaps interviewing for a specific practice or so? In that case, a final interview of this nature can happen. For example, I had interviewed specifically for the Marketing and Sales Practice of McKinsey, so back then I had two rounds of three interviews each and a final 7th interview with the Partner who was building the Marketing and Sales Practice, so naturally he wanted to meet me before making that final offer (was more of a meet & greet than a real PEI)!

Either way, good luck and fingers crossed!

Hey,

It's totally OK to draw from the same stories you are prepping for the PEI part and adapt them for a conversation on Values. And if you already have 8, going to 10 or 12 stories won't make you better prepared. 

If you still want to prepare more, it's probably better to exercise on how to link those stories to different questions you can expect from the PEI/Values section. In my view, you will see that new stories are not truly needed, but you might discover that a slight twist is needed to create a compelling narrative to cover the "creating a great work environment" topic. For example, this might mean creating two versions of Story 1: 

• Story 1A (where, say, you highlight your entrepreneurship during a startup competition in college)
• Story 1B (same background, but you highlight how you kept your team's morale high while doing that!)

Just an important reminder: PEI and Values-adjacent questions from McKinsey Partners and Senior Partners can be tough. They will use the same logical rigor that you can expect from a quantitative interview in a case.
E.g., "This candidate told me three stories about their love for project ownership, but will he be ready to work in a 3-week DD engagement where our team will mostly validate a management case that we can not realistically change and that we will never truly own?"

My tip: make sure that all your stories have a bullet-proof element of "I am a perfect fit for McKinsey". And if you are insecure, book a 15-min consultation to see if a coach can help :)
 

Good luck on your interview, you'll crush it!

PS: Just as a reference for the other candidates, this page shares McKinsey's purpose, mission, and values: https://www.mckinsey.com/about-us/overview/our-purpose-mission-and-values

Yes, you can reuse the same context. Same situation, different lens.

The values discussion is not a memory test where the partner checks whether you used this story in the PEI already. It is a conversation. If a story genuinely illustrates a value, use it. Just make sure you are leading with the value and what it means to you, not just retelling the situation.

So instead of walking through what happened step by step, you might open with something like: "One thing I genuinely believe in is X, and I saw what that looks like in practice when..." Then the story follows naturally.

The deeper thing worth knowing: this part of the interview is less about having the right stories and more about whether you seem like someone who has actually thought about what they believe and why. Partners do this closing conversation precisely because they want to get a sense of who you are beyond case performance. Authenticity matters more than novelty here.

Do not manufacture eight new stories. Use what is real and frame it honestly.

Hello,

It’s absolutely fine to reuse the same underlying experience or context across different questions,  including for the values discussion

What matters is not having completely  different stories every time but how well your story fits the question you’re being asked. If one experience can genuinely showcase multiple dimensions (leadership, impact, values, ...)you can absolutely leverage it more than once, as long as you adapt the angle and emphasis.

The same applies to PEI: you do NOT need entirely different stories for every question. You can definetly reuse a smaller set of experiences and tailor them effectively,  rather than stretching to come up with too many weaker examples.

Quality, depth, and relevance always matter more than the sheer number of stories

Good luck!

Hi there,

Look, the honest answer is that you should try not to, but you still can.

Ultimately, you have to determine how strong your backup story is compared to the main one you've already told in your PEI. 20% as strong? Tell the original. 80% as strong? Tell the new one. There are also different ways of telling the same story to make them appear different.

Given you're heading into a final round at McKinsey, this is worth preparing carefully. The values interview is more conversational and less structured than the PEI... which means it can catch people off guard. A coaching session right now would be time well spent.

For story and fit prep, my Behavioral Interview Course covers exactly this. For a direct run-through of your stories, feel free to book a coaching session. And for the full end to end picture going into finals, the 360 Degree Course is worth checking out.

Yes, I've had this with a few candidates.

They don't always include it, and when they do, they tend to do it for more senior or specialist roles.

In practice, what happens is that the Partner will discuss one of the values and then provide an example of how they've experienced that value. Then they will ask you for a similar story as well. 

If you need help with this, drop me a line. I've also built a PEI targeted course that you can read more about here:

hi! 

the “values” conversation is much less about new content and more about authenticity and reflection, so yes you can absolutely reuse the same underlying story as in your PEI as long as you clearly shift the angle and what you emphasize, there is no strict “no repetition” rule like candidates sometimes think; what partners are really testing here is whether you genuinely understand what drives you, how your values show up in decisions, and whether that aligns with how McKinsey operates, so a strong, deeply reflected story reused well is far better than forcing new but weaker examples, just make sure you highlight different aspects like trade offs, judgment, and what it says about you rather than retelling the same narrative

best,
Alessa :)
