How do I break out of feeling stuck and actually learn how to do full cases?

This point exactly, when you feel like you've reached a plateau, is when most people get coaching. 

A great coach can give you a sense of where you are and what you need to do. For instance, when I run a diagnostic session with my candidates, we do a full case, and I then give them structured feedback on what they're doing well (their strengths, and how to turn them into spikes), and their areas of development (and how to close the gap to being interview ready). 

They then have a clear plan to work on and an understanding of how to work on it. 

I know coaching is an investment, but you don't necessarily need to do multiple sessions if your budget is limited. Even one session can make a huge difference, and in fact, in most cases, the first session is the most impactful one in resetting the expectations of the candidate regarding the interview.

If you need help, do reach out.

Hi there,

I’ve seen this happen to a lot of people, so you’re not alone — it’s actually a pretty normal phase.

What’s going wrong is not your effort, it’s the loop you’re in. You’re trying to “fix all fundamentals first” before doing full cases. In reality, it doesn’t work like that — casing is something you learn by doing, not by waiting until you feel ready.

If I were in your position, I’d change just one thing: start doing full cases regularly, even if they feel uncomfortable or messy. That’s where things start clicking.

But the key is what you do after each case.

Instead of just moving on, ask yourself very concretely:

• where did I get stuck?
• was it structuring, math, communication, or understanding the question?
• what would a better answer have looked like there?

That’s how you “learn fundamentals” — but now it’s targeted, not generic.

On balancing theory vs. practice, a simple way to think about it:
most of your time should go into full cases, with some time on drills (math, structuring, brainstorming) to fix specific weaknesses. If you spend most of your time on theory, progress usually slows down a lot.

On “how do I know I’m improving?” — don’t look at whether you solved the case or not. That’s misleading. Look at smaller things:
are your structures getting clearer? are you less lost during the case? are you repeating the same mistakes or not?

That’s where real progress shows up.

For feedback, even without coaching, you can still make it work — but you need to be a bit strict with your partners. Don’t accept generic feedback like “good job” or “be more structured.” Ask them:
“what’s the one thing I should fix for the next case?”

Also, reviewing good solutions after the case helps a lot — not to memorize, but to see what you missed.

If I had to simplify it:
don’t wait to feel ready → do full cases → use each case to identify one or two gaps → fix those → repeat.

Once you do this for a bit, the feeling of being “stuck” usually goes away pretty quickly.

Good luck!

Hi there,

You're stuck because you're doing this backwards.

The loop you're describing... going back to fundamentals every time you hit a wall... is the exact pattern I see most often. And it gets worse, not better, with more reading.

I highly recommend one coaching session early. This is so you can get the right guidance on what to do AND what not to do in your prep. Right now you're building habits... and the wrong ones. A coach catches these in real time. Peers often can't diagnose WHY you're getting stuck, only that you are.

The example I always use: a lot of people go and read cases for a few weeks before actually casing... that's a waste of time. Same with memorizing frameworks... product, price, company... and just regurgitating. That's also not the way!

To your 3 questions directly:

1. Fundamentals vs. full cases: Do full cases now. Use each one to find your specific gap. Fix that one thing. Don't rebuild from scratch every time you miss something.

2. How to know if you're improving: You need live feedback from real humans. Use PrepLounge's peer casing partners. Free, immediate.

3. Feedback without coaching: I'm going to be honest... this is exactly what coaching solves. Peer feedback is valuable but limited. Peers can't always diagnose WHY things go wrong, just that they do.

Before you spend another week reading: Most Common Pitfalls in Case Interview Preparation — most candidates are working hard on the wrong things.

If you're ready to break this cycle: book a session here. Coaches are a time lever — use them early, not when the wrong habits are already set.

And for the mindset behind all of this, search The Consulting Offer Blueprint on Spotify or Apple Podcasts.

Hi, very common feeling — happens to almost everyone at the beginning.

What you describe is a classic loop:
you try a case → feel something is missing → go back to theory → repeat.

The problem is that you don’t break that loop by studying more.
You break it by doing more full cases, even if they’re not perfect.

You don’t need to “be ready” to start doing full cases. You’ll never feel ready. That’s normal.

Try to keep it simple:

• do 2–3 full cases per week
• after each one, note 2–3 things that didn’t work
• focus on fixing those in the next case

That’s how you improve.

On fundamentals: they come from repetition. Structure, math, communication — they click after doing enough cases, not by going back to theory every time.

On progress: don’t look for big jumps. Look for small things:

• you feel a bit less lost at the start
• your structures are a bit cleaner
• you recover faster when stuck

That’s already improvement.

For feedback, try to be specific. Instead of “how was I?”, ask things like:

• was my structure clear?
• did I drive the case enough?

Also useful to practice with different people.

Overall, you’re probably just overthinking it a bit.
Do more full cases, accept that they’ll be messy at first, and things will start to click.

If you want, happy to help you structure your prep or run through a case together.
