Thanks very much for your advise!
Hi,
It depends on several factors:
Purely case prep requires a couple of months with dedicated 2-3 hours per day.
Also, it's often more about quality rather than quantity:
In that case, you need 40-50 cases depending on the role, office, etc (e.g. MBAs in top schools need just a bit of practice compared to regular candidates. Both because of their knowledge and because the on-campus hiring is not that tough)
If you take a good coach, you can make it in 20-35 cases. The coach will give you the right knowledge. Partners will help you integrate the skill. At the end of the day, it's just a skill that can be trained.
Why do you even need partners and coaches? When you are stressed during the case interview and out of energy having the 3rd case in a row, 90% of your questions and reactions should be fully automatic. Otherwise, it's extremely hard to solve the case, trying in find out what you've memorized from v.Cheng book.
Best!

Usually 100 to 150 hours, ideally spread out over 2-3 months: slow at first, intense near the end.
If you don't work smart, if you don't try to learn from your mistakes and get actionable feedback... it will take longer still. There are no shortcuts. Some people get in with 20 hours; some people also win the lottery. Don't plan your life based on the exception.
Thanks very much for your advise!
