It would be nice if there were some sort of standardized tests for skill competency. Like an employer could state, "we need someone who can handle C at level 5, JavaScript at level 3, and Fortran77 at level 9", and leave it to a third-party to test the candidate in a fair way.
Then the interviews would really be about cultural fit and project interest, not trying to prove if the candidate _actually_ knows C, JavaScript, and Fortran77 well enough.
