Ace the Assessment by Tomas Chamorro-Premuzic on HBR
Great article, however to be effective you need a trained and competent person to manage and assess the results. Often tests are performed which are poorly managed and results analysed by a junior HR person. Summary of the tests are then passed on to Hiring Managers, which maybe not as comprehensive as it should/could be. The system is flawed if not resourced properly and the candidate disadvantaged.
