Are AI interview practice tools actually helping candidates?

Lately I’ve been thinking a lot about AI phone interviews and especially AI practice interviews.

On the good side, practice clearly helps some people feel less nervous and communicate more clearly. That feels like a win.

But I keep wondering:

• Are people getting better at explaining their thinking, or just better at saying what the AI wants to hear?

• Do answers start to sound the same after enough practice?

• And if practice does help, is that leveling the field or quietly changing what we’re actually measuring?

We’re building a free AI phone interview + practice experience, and I don’t have a strong answer yet.

Curious how others here see it especially if you’ve hired with AI tools or used them as a candidate.

Does practice improve signal, or blur it?
