Hi there,
Congrats on your offer! As mentioned in some of the other posts, the standard time for a reply for the Imbellus is within 2 weeks.
For those who are still preparing, I did an in-depth study on the Imbellus. Most of the comments I found online are something like this:
- You cannot prepare – it tests who you are
- Play a lot of videogames
- Don’t waste time
- Be yourself
- Be 80-20
- Take notes well
- Enjoy yourself
Not sure what you think, but I don’t believe that’s very useful. Nor did the several people I coached who had to do the test.
So I worked hard with the candidates that actually did the test and created a guide with everything you need to know on the Imbellus.
This guide will:
- Show you the perfect strategy for each of the 4 Game Scenarios
- Explain every single part of the Game with ad-hoc pictures
- Detail the exact steps to improve in the 5 Skills tested in the game
- Provide you insider information from previous applicants who succeeded in the game
- Reveal the must-know answers to the most common questions on the Imbellus
- Offer you a ready-to-use Excel template to maximize results in Scenario 1 with a detailed tutorial
- Give you a proven template to build the food chain in Scenario 1
This guide will cover every single part of the Game, so you can be 100% confident the day of the assessment, without worrying “I should have prepared better for this”. You won’t need any additional material to prepare after it.
You can download the guide instantly here:

As an extra bonus, I am offering for a limited time the Consulting Industry Cheat Sheet (worth $29) for free with the guide. You will get access to key insights of the 17 most common industries in case interviews.
If you need additional support or have any questions on the guide please feel free to PM me, I am happy to provide extra tips for free.
Best,
Francesco
Thank you for your answer! My process has finished and got an offer 3 weeks ago
Hey! I just got scheduled the WebEx for cases, and then HR said my R1 interview will be scheduled soon. Could you provide some information on dates between each rounds and how long does it take for you to hear back after each interview? Congrats on your offer! I hope I can make it as well.
For both R1 and R2, it took me 1 business day to hear back from the HR. But dates between the rounds were more than a month, since COVID situation got worsen just then. Still, HR lets me know about the scheduling progress in between. Best luck for your interviews!
