In some interviews, cases are given with data and an applicant is required to sift through the data and do relevant analysis. How to best practice for those as they also require practicing technical skills? Thank you!

Hi Ksenia,
how were your interviews?
Best,
André
Hi,
Just to add to the rest, focus focus focus.
1) Quickly write down a) Key asks/needs and b) Key insights/context from the prompt
2) Quickly scan through the provided exihibits (i.e. title, quick chart understanding) and eliminate ones that aren't needed
3) In the subset, identify which tell your story the best...adjust as needed, but you should come up with the 3-4 things you need to state ASAP
This is all about taking a ton of information in a short amount of time, and determining what is most relevant. And remember, the same general rules apply: structure, conciseness, driving forward, being creative, etc.
Hi Ksenia
I would recommend to focus on 5 areas to crack cases when they provide material in advance; I have reported them below with some suggestions on how to prepare for each of them:
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 in the best possible way your time. Assuming 60 minutes for the analysis, a good approach would include:
You should then practice to stick to the time allocated, in order to maximize your final performance.
2. Practice graph interpretation
You will normally have to analyse graphs in a written case. The best way to practice is to take graphs from online resources and use a timer to test in how much time you can understand the key message. McKinsey PST graphs could be good practice for that.
3. Work on quick reading and quick understanding of key information
You will not have time to read and prioritize everything, so you have to understand where to focus. The ideal way to practice is to use long cases such as HBS ones, and practice on reducing the time needed to absorb the key information that can answer a defined question. Quick reading techniques could also help.
4. Practice quick math
You will normally have some math to do in a written case. GMAT and McKinsey PST math should work well to prepare on this.
5. Learn how to communicate your slides/answers
If you have to present your findings at the end of the case, I would apply here the same structures of final sum up in a live interview case, that is:
As you will not be able to double check hypothesis with the interviewer as in the live case before 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:
B) structure the content of each slide
There are three basic components for slides:
Many people structure the title as the mere description of what the chart is telling. A great title, instead tells the implication of the graph. Eg 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:
Hope this helps,
Francesco
Hello Ksenia,
In written case you usually have a pack of 20-30 slides that you need to analyse to answer questions using 4-5 slides and present them to your interviewer.
In order to crack the interview you should consider the following points:
You can find some good examples of written cases online, but I could forward you what I have. Contact me if you are interested.
Hope it helps,
Luca
Hi Ksenia, I think you are talking about presentation cases, where you have 30-45' to analyze the data + 15' to present your solution + 15' of Q&A. Case preparation will be the classical one with 2 additional points to focus on:
I have a couple of well done written cases, feel free to text me for sharing.

Antonello
Hello!
On top of what´s been commented so far, I would practice data analysis (charts, graphs, etc.) using GMAT resources -I would strongly recomment you practice it, since normally it´s very different from the things you have seen before -particularly the data sufficency part-.
There are free exams in the internet that you can use for practice (the one of LBS MBA page, Verits prep, as well as some free trials for courses such as the one of The Economist (https://gmat.economist.com/)
Hope it helps!
Cheers,
Clara
Hi Clara, thanks for the comment. Any recommendation to prepare for interviews with data given in excel and then the interviewer is asked to prepare a data analysis and power point?
Hi,
Here is my approach:
Ask the interviewer for a minute to analyze the chart / table
In your mind formulate the question you have to answer
Look at the chart and define the type (pie chart, line chart, etc). Read the chart title. Read the legend
Analyze the chart / table. Look for: Trends, comparisons, % shares, etc. Look for unusual things (consultants love to integrate these traps in charts) - correlations, outliers, etc
Ask clarifying questions if required
Provide your conclusion. You should not just describe the chart but also derive the conclusions. There should be at least one major conclusion plus any additional conclusions you can make. You can also provide your hypothesis on what can be the root causes / consequences
Based on the interviewer's feedback, prioritize the most important information and define the next steps.
Here are some tips on how you can master that skill:
Read "Say it with Charts" book by Gene Zelazny
Check the chapters on cases with charts in the following case books "Consulting Bible" and "Vault guide for consulting"
Refresh the basic statistics (Most of GMAT prep handbooks have a good summary)
Practice GMAT Integrated Reasoning part (GMAT Official guide or Manhattan prep)
Practice on real MBB presentations. Look at the chart, derive the conclusions, and compare it to the ones on the slide. Best sources to find presentations - various reports and articles on MBB websites, Slideshare
