Best way to prepare for case study interviews? EY McKinsey & Company Bain & Company

1) CaseCoach—check out their free 7-day video program. Supposedly gives you the basics of how casing works and how to do one. If you want more of an intro, also check out Victor Cheng's 12-part YouTube series (it is a bit dated but still relevant) and other random YT videos.
2) Google for MBA casebooks from the top business schools. For example "NYU Stern Casebook PDF" and maybe throw a year in the search if you'd like. I know HBS, Wharton, Darden, UMich, Stern, Berkeley all had good ones. These casebooks often also have very useful intro pages about formulas, high-level details for most industries, types of cases, etc. Main focus is the cases themselves, but check out the other pages too.
3) Network with MBB consultants, particularly those from your school or schools tangentially to yours (similar in size and type, such as Big 10 if you attend a Big 10 school) as they'll be most likely to chat with you. If the convo goes well, you could potentially ask them if they'd be willing to run a case or two with you sometime. If that doesn't work, find competent partners to case with from your school or online (keyword: competent). I know Victor Cheng's website has an online scheduler to help find people looking to case, as does MyConsultingCoach. Alternatively there are probably some online forums on Reddit or elsewhere where you can find people.
4) Run roughly 15-25 cases with these people, or however few or many until you begin to isolate your problem areas to only a few sections of the case. Make sure you're also reciprocating and giving them cases. It's a good way to see how others do a case and also a learning opportunity to see things from the other side for your own improvement.
5) At this point, try out RocketBlocks. It's inefficient to run an entire case just to, for example, practice two problem areas you're having out of a five-part case. RocketBlocks has drills for many parts of the case, such as the initial structuring, brainstorming, mental math, etc. It's much better to target your weaknesses directly and running many drills. They also have some solid lessons on mental math tricks (amongst other lessons that I didn't try but are included in their offering).
6) After each case, you should always be reflecting on your case with where you went wrong, where you did good, how you could improve, and even trying to brainstorm other possibilities of the brainstorming section of the case (assuming there is one in the case you did). A good way to do this is to keep a VERY detailed notebook log of these things that you can always turn to and study/reflect on. Too many people go from one case to the next without truly thinking about what they did wrong and could improve, but this is honestly the most important step where much of the learning and integration happens.

Every other resource is honestly superfluous or a money grab. Sure there are books out there like Case Interview Secrets and Case in Point, but they're really not necessary, and many people end up misreading them to where they then start memorizing the frameworks. I read Case Interview Secrets and found portions of it helpful, so if you decide to read that one just go to the table of contents and pick out specific parts of the book to read. Don't waste your time reading it front-to-back.

Side-note: a good supplementary casebook option is Taylor Warfield's Ultimate Case Interview Workbook. Relatively inexpensive on Amazon and has like 30 cases or so. It's a great option to have when you don't have any partner to case with and even to keep in your backpack if you ever have time to run a quick case on the fly. They're self-cases in the interviewer-led style format (McKinsey-style), but they're really solid cases for as good as self cases get. I would do these when I'd come back late at night from work but didn't have anyone to case with or just wanted something more casual to still keep the practice going.

I was able to land 2/3 MBBs (very close to all 3) practicing like this. I feel like this doesn't need to be said, but don't just target MBB only. There are plenty of other good firms out there like Oliver Wyman, Kearney, EY Parthenon, Monitor Deloitte, Strategy&, etc. Feel free to PM me if you have any other questions!

This is soooo helpful. Thank you for sharint.

Practice cases with a buddy

Sorry, for 1) I meant Crafting Cases 7-day free course*, not CaseCoach. I know CaseCoach also has solid stuff, but I'm not sure if it's free, although I do know BCG provides it as a resource once you're in their recruiting process.

Google and YouTube are your best resources. Practice examples cases and go through as many practive interviews as you can.

Thank you so much!
