No, I mean just like companies would like to see a sort of IQ test results for applicants, I'd assume applicants would like to see a sort of employment-worthiness test for the companies. Previous work history here could be the history of that particular aspiring company of hiring people and people leaving the company.
Ah, I see, I think companies being far fewer than people are more able to operate on reputation in a way that would be impractical for general mass of individuals. The companies can and do pay PR to try to influence that reputation, as can individuals, and many high profile individuals do in fact hire PR. Glassdoor is one public source of info, but there is generally quite a lot of gossip around companies. People can reach out to current employees of an company like employers can reach out to previous employers of an individual and I've never had an interview where I was unable to ask the interviewer questions about the company.
Perhaps a proxy for a corporate IQ test would be net earning per employee which is often pretty public information.
