That's a great question. 

Realistically speaking, you can't develop an answer for every possible question. So ideally you have a set of 4-6 stories that you can then calibrate live during the interview to fit that dimension. 

Practically, the way you do that is that you run drills with someone to ask you these questions and test your ability to adjust the story live. 

For anybody who is looking into the PEI topic, I recently released this end-to-end course covering PEI that contains the most often asked questions for the PEI. More on it here:

With the exception of the second how question, I would say the questions are broadly the same.  McKinsey interviewers have guiding questions for each PEI dimension but at the end of the day, it's down to their discretion on how they ask the question.  My advice is not to prepare for the longtail of questions/nuances and instead think about what are the 3-5 underlying competencies that each PEI dimension is testing for.  You're absolutely right that its important that you are actually answering the interviewers question and a good way to do that is to first frame an answer with the summary of your story.  For example, “you've asked me about solving a conflict amongst stakeholders, I'm thinking of [recent story] where I had to do x, y, and z - could that be an appropriate example?”.  By doing this, you're already telling your interviewer that your story has the underlying competencies (i.e., x, y and z) that they are looking for in your story.  The biggest anxiety for a McKinsey PEI interviewer is that they spend 15 mins listening to your story to realise that it didn't answer what they were looking for and you've run out of time!

Hi there,

This is a common misconception that is unfortunately also perpetuated knowingly by coaches on PrepLounge and elsewhere to sell their advice. 

All you need to know in brief:

• There are actually 4 PEI dimensions since Entrepreneurial Drive is replaced by Courageous Change and it is those 4 only
• Each dimension has very specific evaluation criteria with an associated score sheet that interviewers are looking for, regardless of how the initial question is framed or asked. There is no leeway for the interviewers with regard to this evaluation
• Coaches and websites that discuss more than the 4 PEI dimensions and related questions either do not know and copied their “wisdom” from another ignorant source or do this on purpose to sell their courses or services

Focus on the information in this article, where I discuss the PEI and the dimensions in detail and prepare stories that hit most of the criteria I outline and you will be fine. :-)

Cheers,

Hi there,

This is a great question. First, to provide some reassurance - the PEI questions are generally quite broad. Not everyone will have worked with clients, for example, and so they're very unlikely to ask a question that is focused on clients. Not everyone will have been in a situation where they need someone to give them data - and so again they're very unlikely to give you a question that specific. 

That being said, I always recommend that everyone prepares at least two distinct stories for each of the now four PEI domains (leadership, personal impact, entrepreneurship and courageous change). This will give you the ability to flex should one of them not be quite right. These stories should be quite broad (e.g., how have you successfully led a team; when have you successfully navigated a disagreement with someone), rather than narrow (e.g., when have you had to lead a team where you had a disagreement with your manager over the direction of work). 

Then, when you're asked a question you should be able to flex for the most appropriate answer. 

Good luck!

Hi there,

It's better you have at least 3 stories for each dimension. You need to practice flexibility on how to frame an tell your stories. In general, interviews should frame a more open and high level question to let you select your best story along the dimensions they will be evaluating.

Hello,

Preparing 2-3 stories for each dimension is a great approach. The PEI questions are quite general, and should allow you to tailor them to your specific situation. In the example you gave, not everyone will have worked with clients (or needed to obtain data from them), so those sorts of questions are unlikely to be asked if you don't have the relevant industry experience, for instance. The first and last questions, and the fourth and fifth questions respectively are broadly the same, and it should be easy enough to adapt your answers between them (for instance, by making sure at least 1 of your conflict stories has a stakeholder involved).

I know it sounds easier said than done, but if you are preparing 2-3 different (varied, deep) stories per dimension, you should be able to dig out enough details to tailor them to the specific flavor of question asked. You could look into getting some coaching / feedback from an experienced friend as to whether your stories are covering sufficient ground. Other than that, look up common PEI questions, and just see if you can answer them with your stories (omitting the ones that are clearly not relevant in light of your experience).
