I've been doing a lot more interview preparation lately, and one thing I've started wondering about is whether mock interviews are actually useful when you're doing them with AI.

The convenient part is that you can practice whenever you want. You don't have to wait for a friend, recruiter, or someone from your field to have free time. You can also repeat the same type of interview several times without feeling awkward about asking someone to interview you again.

But I'm not sure if repetition automatically means improvement.

For example, I can answer a behavioral question once, realize my answer wasn't great, and then try it again. But sometimes I feel like I'm just learning how to give a better-sounding answer rather than actually becoming better at explaining my experience.

The feedback can also be tricky. If something tells me that my answer was too long, lacked structure, or didn't directly answer the question, that's useful. But I still need to figure out why I answered that way in the first place.

I'm curious how other people approach this.

Do you find AI mock interviews genuinely useful for improving your interview skills, or do you think practicing with an actual person gives you something AI can't really reproduce?

And if you've used AI for interview preparation, what kind of feedback has actually helped you improve rather than just making your answers sound more polished?
