Building and telling a strong story
The STAR shape, the dimensions firms probe, your story bank, and the deep follow-up of the PEI.
Key takeaways
- Build a story bank of about eight real stories: two for each dimension.
- In each McKinsey interview, part of the time (often up to about 20 minutes) is a Personal Experience Interview.
- What was your specific role? What did you do yourself?
- Why did you choose that approach? What else did you consider?
- Who disagreed, and how did you handle it?
The fit interview asks about your real experiences and your motivation. At McKinsey it is a large part of every interview. At many other firms it is shorter, often 10 to 15 minutes, but a weak answer can still end your chances. It rewards preparation, because you can build and rehearse your stories in advance.
Tell each story in a clear shape called STAR: the Situation (the setting, in one or two lines), the Task (what needed doing and why it was hard), the Action (what you personally did, in detail), and the Result (what happened, ideally with a number, and what you learned). Most people rush the Action, which is the part the interviewer cares about most. Say "I", not "we", when you describe what you did.
| Current name | Older name | What a story should show |
|---|---|---|
| Connection | Personal Impact | You influenced or persuaded others, built a relationship, or worked through a disagreement |
| Drive | Entrepreneurial Drive | You took initiative, pushed through obstacles, or created something without being asked |
| Leadership | Inclusive Leadership | You led a group, including people different from you, toward a shared goal |
| Growth | Courageous Change | You adapted when plans changed, challenged the status quo or drove a difficult change, and learned from setbacks |
So-what
Invitation emails and interviewers may use either set of names. Other firms probe similar themes under different labels.
In each McKinsey interview, part of the time (often up to about 20 minutes) is a Personal Experience Interview. The interviewer picks one dimension and asks for one real story, then asks many follow-up questions: what exactly did you do, what were you thinking, what did the other person say, what would you do differently. Stories that are shallow or not really yours break down quickly under this. Real, specific, well-structured stories hold up.
Key idea
Build a story bank of about eight real stories: two for each dimension. McKinsey generally expects a different story in each interview, so one story per dimension is not enough across several rounds. Other firms are more relaxed and let one strong story answer several questions, but eight gives you room everywhere.
Follow-up questions to rehearse for every story
- What was your specific role? What did you do yourself?
- Why did you choose that approach? What else did you consider?
- Who disagreed, and how did you handle it?
- What was the hardest moment?
- What was the result, and how do you know?
- What would you do differently next time?
You have interviews with McKinsey across two rounds. How many stories should you prepare?
