Hi, I have a 90min Case study Interview with EY (Supply Chain Consulting) - UK.

Any ideas on what to expect and how to prepare?

Will this be an Interviewer led case study or a written case study format?

Thanks

Hi there,

Given your comment below on Adi’s reply, it is going to be a written case/panel.

The key areas you will have to cover to prepare for that interview are the following.

1. Learn how to define a plan of action and stick to that

The first thing you should do in a written case is to define a plan and allocate your time in the best possible way.

Assuming 30 minutes for the analysis, a good approach would include:

  • Initial quick reading – 5-10 min (this may depend on the amount of material)
  • Structure the approach – 3 min
  • Make slides/answer to the questions adding detailed analysis and math – 15-20min
  • Final review – 2 min

You should practice to stick to the time allocated to maximize your final performance.

2. Practice graph interpretation

You will probably have to analyze graphs as part of the data provided. The best way to practice is to take graphs from online sources and use a timer to test in how much time you can understand the key message. McKinsey PST graphs are good practice for that.

3. Work on quick reading and quick understanding of key information

You won’t have time to read and prioritize everything, therefore you have to understand where to focus. The ideal way to practice is to use long cases such as HBS ones. You should then learn to absorb the key information of the case. Quick reading techniques could also help.

4. Practice quick math

You will probably have some math to do as part of the data analysis. GMAT and McKinsey PST math should work well to prepare for this.

5. Learn how to communicate your slides/answers

When you have to present your findings in the second part, I would suggest the same structure used for a conclusion in a live interview, that is:

  1. Summarize the main questions you have to answer
  2. Present your proposed answer and detail the motivation behind
  3. Propose next steps for the areas you have not covered

As you will not be able to double-check hypotheses with the interviewer while you prepare the presentation, you should clearly state when you are making hypotheses and that you will have to verify them with further analysis.

When you have to prepare slides I would also recommend to work on:

A) Structure the order of the slides

Normally the structure for a 5-slide presentation is the following:

  • First slide summarizes the question and provides the answer
  • Second, third and fourth slide have the supporting arguments for the first slide
  • Fifth slide has the next steps

B) Structure the content of each slide

There are three basic components for slides:

  1. Title
  2. Chart or data
  3. Label for chart

Many people structure the title as the mere description of what the chart is about.

A great title instead shows the implication of the graph as well.

Example: say the graph is showing a cost structure for a division.

  • A bad title would be: Cost structure from 2005 to 2015.
  • A good title would be: Cost structure of Division XYZ is not sustainable”.
  • A great title would be Cost structure of Division XYZ is not sustainable due to ABC, assuming you have insides on the cause.

The rule of thumb for the title is that if you read all the titles of the slides together you should get a clear idea of what is going on.

C) Present the slides

When you present, I would suggest the following steps for each slide:

  1. Introduce the slide:Let’s move to slide 2, which will show us why we have an issue with this division
  2. Present the main message of the slide: “As you can see, we have a cost structure which makes unfeasible to be competitive in this market
  3. Provide details: “The graph, indeed, shows how our fix cost is XYZ, while competitors can benefit from economies of scale. Indeed…

In terms of how to prepare, I do a session exactly on that.

Before the session, I can send you the data source to work on. We can then simulate the written case during the class, reviewing step-by-step all the improvements needed.

Please feel free to send me a message in case you have any questions.

Best,

Francesco

Hey there,

You will face a written case. Here are a few tips for this situation:

#1 Already have a plan when you go in for the written case

Since time is usually limited, you should have a plan on how long you want to spend on each task of the assignment beforehand.

#2 Focus – quickly separate crucial information from the noise

Written cases usually present you with an information overload that you need to sort out

#3 Graphs and charts – interpret and distill key insights from graphs and charts

Written cases bombard you with charts, graphs, tables, and other visual depictions of data that you should use to test your hypotheses. Learn how to quickly read and interpret them

#4 Math – quickly draft equations and conduct pen-and-paper math

Get into the habit of quickly setting up and simplifying calculations

#5 Storyline – draft a compelling storyline and tell it with visually appealing outputs

Create a top-down storyline of your recommendations. State your primary recommendation, then use supporting arguments to strengthen your position

#6 Presentation and defense – communicate and defend your recommendation top-down

If you have to present your findings at the end of the case, follow the top-down approach of your slide deck. Be confident and engaging when going through your recommendation and supporting arguments.

I have written in great detail about the written case interviews in this free article here: https://strategycase.com/how-to-crack-written-case-interviews

All the best!

Cheers,

Florian

Hi there,

This very much sounds like a written case study.

It's unfortunate because there really aren't many practice cases out there :/

That said, I have a number I'd be more than happy to share with you! What I generally do with my candidates is, give them a written case x hours before our scheduled session (adjust # of hours based on the specific interview they're going to have), and then review their work during the session (as well as talk through tips+tricks to get better).

Hey,

Dont hesitate to clarify details with HR such as written case or interviewee led.

Have you applied for an experience hire role in their consulting practice?

Supply Chain is my specialty so feel free to message to discuss if you need any prep help.

There are plenty of threads in the Q&A forum on case interview prep so please search broadly for that.

Hi there,

I agree - you should probably prepare for the written case. The other coaches gave you very good hints on how to approach it the best way.

Cheers, GB

Hi,
I confirm it will be a written case. The preparation will be the classical one with 2 additional points to focus on:

  • 80-20 prioritization: quickly navigate an important amount of data to find what really matters to the case resolution;
  • Executive summary: develop 1-2 pages to present that sum-up the problem and your recommendations.

I have a couple of well done written cases, feel free to text me for sharing.

Hey, can you confirm if you had received a written case or a verbal scenario from the interviewer?

Do reach out to their internal Talent team to get answers on the structure of the case as they should have offered this information

Preparation should be similar to other Big 4 cases which you can find on the Preplounge case library
