I’ve tried general AI tools like ChatGPT and DeepSeek, but they’re not really designed for interview scenarios. Having to manually input questions each time makes it impossible to get real-time responses during a case, which just doesn’t work for fast-paced mock interviews.
I recently discovered Ninjafy AI and gave the free trial a shot. So far, it feels pretty solid, and I’m about to head into formal interviews soon. Has anyone else used it? Would love to hear your feedback—please, no ads!
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 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,
Sebastian
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.

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
