Is it a good or bad sign when the interviewer had many questions in the PEI part?

many questions in PEI is usually a good sign, but it depends on the type of questions.

How interviewers use questions in PEI
Interviewers are not trying to “chat”. They are stress testing.

• They ask questions to probe depth, ownership, and judgment
• A good story invites follow up because it has substance
• A weak or shallow story usually dies quickly

Good signs
Many questions are positive when they are:

• Zooming into your specific decisions, trade offs, and rationale
• Testing leadership moments, conflict, or pushback
• Asking “why” and “how” repeatedly
• Exploring consequences and learning

Neutral to bad signs
Many questions can be negative if they are:

• Clarifying basic facts you should have made clear
• Trying to understand your role because it is vague
• Reframing the situation because the story is disorganized

In that case, questions are compensating for a weak structure.
Few questions is not automatically good.

• Very few questions can mean the story is excellent and complete
• Or it can mean the interviewer already decided it is weak and moved on

You cannot reliably tell which one it is in the moment.

• Number of questions alone means nothing
• Depth probing is good
• Clarification probing is a warning sign

Hey there! I wouldn't read too much into it. There are cases when they ask many questions to better understand/challenge the story and cases when they ask a few clarifying questions, but the number of questions itself is not necessarily an indicator of whether the candidate did well / did not do well in this section.

Fingers crossed for you!

Hi there,

Not necessarily. The number of questions in the PEI part on its own isn’t a reliable signal of how well you did.

In McKinsey interviews, lots of follow-up questions can mean different things. Often, it’s actually a positive sign that the interviewer is engaged and wants to understand your thinking and behavior more deeply. Strong PEI stories are usually probed because interviewers want to test judgment, ownership, and impact rather than just accept a surface answer.

At the same time, many questions don’t automatically mean the story was weak or poorly told. Interviewers are trained to dig, even when the initial answer is solid. What matters more is the quality of your responses to those probes — whether you stay structured, consistent, and reflective.

A more telling signal is how the questions feel:

• If they’re digging into decisions, trade-offs, and consequences, that’s often a good sign.
• If they’re repeatedly asking for basic facts or clarity, it may indicate your initial explanation wasn’t clear enough.

Overall, don’t over-index on question count. Focus instead on whether you answered calmly, clearly, and with ownership. That’s what drives PEI evaluations.

hey there!

Generally it is a good sign if the interviewer asks many follow up questions in the PEI, it usually means they are engaged and want to really understand your role and impact, at McKinsey this often signals interest rather than doubt, it only becomes negative if questions keep circling because basics were unclear, so as long as the questions go deeper and not back to clarifying facts you are usually in a good spot, happy to help more if you want to sanity check a story.

Hi there,

There's no definite answer on whether this is good or bad. Each interviewer has their own style and curiosities. It's best to not make conjectures at this point.

Lots of questions in PEI can be either good or bad. It depends on the type of questions.

When it's usually a good sign:

The interviewer is digging deeper into your story. They ask things like:

• "What were you thinking at that moment?"
• "Why did you choose that approach over other options?"
• "How did the other person react?"
• "What would you do differently now?"

This means your story hooked them. They're testing your self-awareness and judgment. They want to see how you think, not just what you did. This is what a good PEI looks like.

When it might be a bad sign:

The interviewer keeps asking basic clarifying questions. Things like:

• "Wait, what was your role again?"
• "Who was involved in this?"
• "What exactly was the problem?"
• "Can you walk me through what actually happened?"

This usually means your story wasn't clear. They're trying to understand the basics because you didn't lay them out well. That's not a good sign.

How to tell the difference:

Think about when the questions came.

If they asked clarifying questions early and then moved to deeper "why" questions, you're probably fine. You just needed a bit more setup.

If they kept asking clarifying questions throughout, your story likely wasn't structured or specific enough.

Here's the real test:

Did the conversation feel like a discussion or an interrogation?

Good PEIs feel like a back-and-forth. The interviewer is curious and engaged. You're thinking on your feet and showing depth.

Weak PEIs feel like you're being pulled through your own story. You're explaining and re-explaining instead of reflecting.

A quick tip for next time:

Start every PEI story with a 30-second setup: the context, your role, and the challenge. Make it crystal clear. Then go into the actions and results. This reduces clarifying questions and lets the interviewer jump straight to the deeper stuff.

Hi,

It's totally fine! McKinsey interviewers are trained to ask probing/follow-up questions to really push your self-reflection. So it's actually a good sign they are asking questions.
