Has anyone tried any of the AI interview tools for MBB prep?

Hey there, 

just to make sure I understand this correctly: Do you want to use those tools for prep or for the actual interview? 

For the actual interview (online only): I would strongly encourage you to not do that. Trust me it will show and you are ruining something that you have worked for for so long. Rather put in the work for the prep and rock the interviews that way :) 

For Prep: I would use this very selectively, largely because I think it omits the things that make cases so hard in real life. Most cases are not terribly complicated and the math is fairly straightforward. What makes them hard is that there is another human being sitting in front of you that is making you nervous and staring holes into the back of your head while you try to calculate something on a piece of paper. This is were most candidates perform significantly below their true potential. You won't be able to practice that with an AI tool. In case you do not have anybody available, the AI tool might be better than nothing but it will not replace the prep you need to put in with your friends/colleagues/coaches. 

Hope that helps! Reach out if anything is unclear. 

Best,

Hi there,

The problem with the most common AI models is that their output is based on a big average. In the case of case prep, they rely on the standard case prep materials (which are mostly wrong - there is a reason why 99% of consulting applicants fail) to generate insights.

Having tried and tested the common models on the different case elements, I found that they fall short, mainly on framework creation and brainstorming. They are good for case math problems and okay for chart interpretation. Since top consulting firms hire only around 1% of applicants overall or 10% who make it to the interview, creating average insights is not enough.

More advanced reasoning models are better at creating frameworks and brainstorming but they are still not up to par with an excellent candidate, who would get an offer.

I have no reason to believe, however, that this will not change over the next 1-2 years, in line with completely new hiring requirements for consulting firms and overall fewer entry-level positions due to the impact of AI.

The whole consulting recruiting and way of working will change significantly and very few people have this on their radar yet...

Cheers,

Florian

Hi there,

I would be happy to share my thoughts on your question:

• First of all, although I haven't tried it, I don't think that as long as interviews are still conducted by humans, it's better to prepare with an AI than with another person.
• Moreover, however, if you find yourself in a situation where you don't (always) have another person to prepare with, it could be a useful substitute.

You can find more on this topic here: How to succeed in the final interview round.

If you would like a more detailed discussion on how to best prepare for your upcoming applications, pre-interview assessments and/or interviews, please don't hesitate to contact me directly.

Hi,

In my opinion, AI tools are complimentary in your interview preparation process.

In general, the tools are still to generic to be your only source of preparation and it is difficult (yet!) they simulate the same interview environment as an experience coach can do.

Other AI tools you can have a look at are MBB, Krakit and CasewithAI.

Hey!

I used CasewithAI in my interview preparation but felt that it fell far short vs doing in person cases with partners. 

Happy to chat through my experience.

Hey there, 

I am still yet to find an AI tool for case interview practice that has the right level of depth, nuances, personalization, and specificity to meet the performance bar to pass case interviews 

I am sure in the future they will get better, but for now, I find they are not quite there 

All the best

Consulting interviews are not about having the perfect answer but about demonstrating how you think, how you handle a potential client situation, and how you build rapport with the interviewer. 

AI tools can be helpful to a certain extent, but ultimately, you need to practice with real people to refine your approach.

Best,

I have not used it - but I am pretty confident AI tools still cannot capture the full nuance of the live interview.

It will happen one day, but if AI is that sophisticated, then it's more worrying for consulting firms themselves :)

I recently tried casetutor.com and I thought it was phenomenal. 

They’ve partnered with top case interview coaches and built an advanced voice AI platform that simulates real-life mock interviews. You can practice as many reps as you'd like, whenever you want, and with an AI-driven interviewer that is conversational, so it provides realistic back-and-forth dialogue and personalized feedback, which is missing from the other tools I've looked at. Definitely worth checking out

AI is as good as the training material they get. Since 95% of the available material is bad, and most people don't know the difference between a good answer / structure and a bad one, most likely AI is providing you with weak (if not wrong) suggestions.

Hey there 🙂, AI interview prep tools like Ninjafy AI and others are becoming more popular for MBB case prep, and while they can be helpful for structuring answers, brainstorming frameworks, and improving mental math, they still have some limitations—like lacking the real-time, adaptive thinking that a human interviewer provides.

I've heard from some candidates that Ninjafy AI does a decent job at simulating a case flow, but it's still best used as a complement to live mock interviews rather than a replacement. If you're using it, try pairing it with real case partners to get feedback on communication and presence, which AI tools struggle with.

Would love to hear your experience after using it more—do you feel it helps with spontaneity and real-time thinking? Best, Alessa 😇
