Invitation for a "Written Case" Interview

Question

Hi all,

I’ve received an invitation for a written case interview, and the format will be as follows:
First, there will be a normal interview. Afterwards, I’ll receive a dossier with different materials (texts, graphs, etc.). I’ll then have one hour to prepare a short flipchart presentation, after which I’ll present my key insights.

Does anyone have experience with this type of interview? I haven’t been able to find any similar cases to practice with.

Would anyone be willing to share some example cases?

Thanks a lot!

Hi there,

You've come to the right place! I have 30+ real written/take-home cases across a ton of firms, several with sample presentations and answer walkthroughs. Shoot me a message and I'll send some over.

One quick note on the prep: for a dossier style format like this, lead with your recommendation. Don't walk them through all the data... give them a clear point of view, supported by the analysis. Your flipchart should be conclusion first, then the 2 or 3 things that back it up. Think real client presentation, not live case interview.

Answer 3

Written case interviews test the same things as a spoken case, just with more pressure on synthesis and communication.

On the preparation hour: do not try to cover everything in the dossier. There is more material than you can handle in an hour. Pick the two or three insights that actually answer the core question and build everything around those.

On the flipchart: lead with your conclusion, not your analysis. One idea per page with supporting evidence. No data dumps.

On the presentation: speak to your logic, not your slides. They can read the flipchart. What they are watching is whether you can defend your thinking when they push back.

For practice: take any business article, give yourself an hour, and produce a three to four page flipchart with a clear recommendation. Do that a few times and you will get the feel for it.

Most candidates walk in underprepared for this format. A clear structure and a strong point of view will make you stand out.
