My Consulting Offer Program

I think they're ok, but nothing special. I put them in the tier of Case Coach, Management Consulted, etc.

I.e. fine for a beginner, but not great at getting you to the advanced stage.

Here's some reading to help with your case prep:

The Most Common Pitfalls in Case Interview Preparation
 

Dos and Don'ts in a Case Interview
 

How to Shift Your Mindset to Ace the Case
 

Candidate-Led Cases: What to Expect With Example Cases

Hi there,

Maybe I am wrong but last time I checked they still use a framework memorization approach to case interviews which is among the most detrimental advice there is.

I have not seen their courses, however!

You could directly ask them about the course curricula and then get back with the information.

All the best,

Florian

I've had a couple of candidates who switched from that to PrepLounge. 

Haven't heard anything bad, but also haven't heard anything specifically good.

If you have the luxury of time, then do test it out. 

Hope it works out for you!
