McK exhibit reading

mekko_nf_1.png

For a chart like this where they are asking which segment should we focus on, should we comment on each vehicle type? I see people commenting on what's largest , what's smallest..but would it sound like I'm reading everything on the chart in such cases where there may be 2 large segments and 2 small segments. Should I only comment on what's largest and growing?

Let me be very direct: they are doing this wrong. Interviewers don't want candidates to describe the chart for them. Any reasonably trained business undergrad is (or should) be able to do that. They want much more. They expect candidates to:

  1. Find relevant insights. Insights are not on generic trends, but on things that are “odd”, or that don't come immediately from the chart, but require you to do a little bit of thinking.
  2. Relate the insight with the the case objective. Is this good or bad for them? Is there an oppportunity? (if you can't relate it to the case objective, then it is not an insight, but just a curious observation that you should disregard)

So going back to the chart, I notice a few things:

  • Foreign Light trucks have a +50% jump in 2016. This didn't happen in the other categories. So something “odd” happened in that year and we would want to investigate further.
  • Light trucks (foreign and domestic) gained share significantly in 2016. One hypothesis is that truck demand grew so much in that year that the country needed to import much more just to meet internal demand. → do you see what I did here? I combined the 4 segments into 2 grouped segments.
  • You could add that the growth in share of trucks cannot be only explained by the decrease in autos, but is also the result of its own growth. And also that the increse in light trucks can't be explained by exchange rate fluctuations (and unlikely to be import duties) as you don't have the same impact on foreign cars that actually decreased.
  • I don't know the case objective here, but let's assume the company wants to expand light truck capacity. This insight would support the investment case (assuming it's not a one off thing).

Let me say this again: this is the biggest mistake I see in exhibit analysis - just describing what the chart says without stating any insight and without relating it to the case objective.

Hey there,

Pedro is right. You should only zero in on insights that are both

  • outliers 
  • relevant in the case context

and then interpret and discuss them in the context of the case objective (the so-what?).

Don't forget that a McKinsey “exhibit reading” question is about conceptual thinking. As a result, I usually encourage a candidate to share both observations as well as implications. Observations shouldn't be the bulk of the time spent but it is an important way to align with your interviewer. If you are not aligned on the observations, you are likely misaligned on the implications. For the implications, don't just offer one hypothesis but multiple. Again, it's conceptual thinking, your ability to conceptualise the problem is what is being assessed. Good luck!

Pedro is 100% right. No interviewer wants you to repeat what is on the chart. Instead focus on the insights you can draw from the chart.

These could be points such as :

  • The sales of vehicles has grown yoy in the US
  • Growth in recent years have been driven by trucks which has outpaced autos in the last few years and both domestic and int'l manufacturers have benefitted
  • Users are both replacing autos with trucks and buying new trucks instead of autos given the high growth seen
  • Share of foreign vehicles has shifted from autos to trucks in line with the US market

Focus on what the chart is telling you and not what is on the chart.

Best,

Udayan

Hi there,

This is indeed an interesting question which is probably relevant for quite a lot of users, so I am happy to provide my perspective on it:

  • Generally speaking, you should not comment on every segment presented in an exhibit but solely on the outliers that are relevant for answering the question.
  • While I agree with what other coaches said in general, I would still advise you not to forget about the overall process of a proper exhibit analysis:
    • Taking a short period of time to analyze the exhibit on your own
    • Asking clarifying questions if applicable
    • Shortly describing the exhibit (in case the interviewer has not already done it)
    • Focusing on they key insights and putting them into case context

In case you want a more detailed discussion on how to best approach McKinsey exhibit analysis questions, please feel free to contact me directly.

I hope this helps,

Hagen
