Asking about employee turnover is a legit job interview question.  No point in going through that red flag to get to a shitty job.

I agree but how do you verify that they're not lying

If I'd be the guy hiring I'd just lie about it in the interview.

I just do the bathroom test

You can tell a lot about a workplace from its bathrooms, if they cut corners with costs for example etc, they might put up a facade in the offices but they always forget about the toilets.
