How to know if someone is lying on whether they have actually designed experiment in real life and not using the interview style structure with a hypothetical scenario?

Hi,

I was wondering as a manager how can I find if a candidate is lying about actually doing and designing experiments (a/b test) or product analytics work and not just using the structure people use in interview prep with a hypothetical scenario or chatgpt hypothetical answer they prepared before? (Like structure of you find hypothesis, power analysis, segmentation, sample size , decide validities, duration, etc.)

How to catch them? And do you care if they look suspicious but the structure is on the point? Can we over look? Or when its fine to over look? Bcz i know hiring is super crazy and people are finding hard to get job and they have to lie for survival as if they don’t they don’t get job most times?
