Grading system at McKinsey

Hi,

It is well known that PEI and case solving are key parameters that McKinsey uses to assess the performance of a candidate. However, I was wondering if the result from Imbellus test is also taken into consideration for a more holistic assessment so to say?  what is the distribution of each parameter in the scale of importance? e.g. PEI-Case-Imbellus =  40%-60%-0% etc

Thank you all in advance!

Hey there,

You need to consistently pass the bar in all interviews as well as demonstrate spikes in certain areas. 

For the Imbellus, it depends on the office. Some use it as a screening device before the interviews, others use it in combination with the first round or even all interview rounds. In general, it counts less than the 2 interview components.

If you want to learn more about the case and PEI, check out the following articles:

Cheers,

They are not interlinked as you suggest. You have to pass the bar for each of those stages independently. 

If you’re below the bar in either one, you’re not going to progress. For example, if you do very poorly in a case (fingers crossed that won’t happen), it won’t matter if you had a 99th percentile Imbellus.

Hope this helps. Best of luck!

Hi there,

Imbellus has not impact as to whether you pass any given interview round.

The Imbellus test is a screening tool. 

Ultimately, every single round is independent of the prior rounds (except for where they're looking for pre-identified weaknesses). The bar needs to be passed each and every time.

Treat them all as equally important!

You have to pass all of them. Period. This is not a weighted average.

If you get a “red flag” on the PEI, it doesn't matter how good the case is, and vice-versa. So it's basically about passing everything. 

Imbellus won't get you an offer, as its purpose is to understand whether or not it is worthwhile to interview you. 
In an extreme scenario (where they are really struggling between two candidates for a single position), they could in theory look at the imbellus result as an additional datapoint, but you would need to have a great performance for that to make a difference (in that specific scenario).

The imbellus test is not really part of key decision making the way case and PEI are. You have to do well in case and PEI to get the offer, there is no getting around that. Imbellus is more of a sense check tool.
