Hi, I will have a third round interview with BCG which will be in the form of a written case, does anyone have any experience on written cases are and how to prepare for that compared to regular cases? Many thanks!
It'll be quite similar to an oral case, but you might be expected to fill in some graphs, organise some slights and write a summary before presenting to someone typically at a level around Manager.
I'd make the following recommendations: - Be very aware of time. Do you have enough time to do calculations to one decimal place, or will you need to estimate?
- Make sure you've thought through how you are going to communicate the story. Do you have the slides with good context, an answer and then a logical proof behind it?
- Sounds a simple one, but write clearly and don't make a mess. Draft up a chart on scrap paper before editing a handout if you're not sure, for example
I had written case in first round of BCG. The biggest challenge was to separate important information from red herring, as they are giving to candidates a folder with lots of documents - some of them are relevant, but most - are not.
If you have the same format, then understand the problem, draw you issue tree, and collect the informarion based on specific needs. You'll be out of time if you try to read and analyze everyting.
Than candididate needs to do extensive calculations (try to find the shortcuts, otheriwse you'll be out of time).
Finally candidate needs to draw a couple of slides and show off communicatioin skills to deliver solution to interviewer.
