Testing is a very important tool to evaluate a new hire. It should be done. But unfortunately the tests on Upwork were super misleading. Way too easy to manipulate. I once hired a freelancer that scored #1 on the English proficiency test, yet could barely type a coherent sentence.... So I actually used the test results, but not to evaluate skill. I used them to evaluate honesty. Super high scores, usually mean cheater. Lower scores mean honest.
