Quite a few stages. Started with basic application and eligibility questions, followed by a few online aptitude tests. Panel interview in January and assessment center in March. If you can pass the initial tests you are smart enough to do the scheme, the two following interviews are more about whether you fit the scheme from a personality perspective. I.e. Can you digest large amounts of info quickly and react to sudden changes; How good are you at working with and influencing others (don't be dominating/doormat); Do you have a can-do attitude (given the current state of the NHS, this is a must!)
