Lmao, the UK is like last in the list for anyone of the calibre that qualifies for this. The 3 applicants they got probably got accepted elsewhere and didn’t even move to the UK.
I can say with relative certainty that at least some applicants went for this visa as a long shot because they had other reasons to move to the UK and this gave a more flexible visa than the Skilled Worker visa (like the ability to change jobs without getting re-sponsored).
It was never gonna be the main reason for anyone to move here and completely misunderstood how academics make decisions about their location.
