The short answer is yes, but those studies are kept internal to the companies. The longer answer is we can only study the people that joined the company and failed to perform rather than those that COULD have been outstanding but our interview process selected them out. So there are flaws, of course. I'm not sure how you could do the latter unless the biggest companies shared their data and compared scenarios of "Candidate X failed an Company Y interview, but then later got a job at Company Z, and thrived". Also you'd be working against the bias of "Well, that just means that the Company Z is easier to work at". There are just too many variables, team to team. Part of the problem is even within these massive companies there is a huge diversity of types of jobs, and an engineer who thrives on working on Google AdWords might fail on the SpannerDB team (to pick two random examples from not my company)
