This seems like the games and aptitude tests that some employers make you complete near the start of the process. There is a difference, currently most tests are critical thinking tests or personality quizes that may not match up to the skills you need for the given job. But the important difference is one of test design, not whether it is on the blockchain or not.

The UK's Coronavirus Job Retention Scheme (where people are put on furlough and the government contributes to wages) seems to have damped the creative destruction usually seen in recessions. To use a basic example, assuming there will be more remote work in the future compared to pre-COVID times, there will likely be fewer people who commute and fewer people who buy sandwiches at Pret.
Perhaps a better solution is to make furlough portable, so that workers can read the writing on the wall and be part of the reallocation we are soon to see. [1]
