How could you possibly get evidence for it if it is the case?
The lawyer, in a civil case, should already have all of the evidence they need gathered by the HRC.
States, countries, etc. will differ of course.
I do wonder what it'd be like to have something proved and to have an administrative judge tell the company to hire you anyway... Wouldn't that be super uncomfortable?
And you'd need to have much bigger sample size than 2.
I think some do, but probably most don't. Agreed a sample size of more than 2 is better but it will take enormous resources to create those resumes and matching profiles elsewhere in linkedin etc.
