With regard to those wondering about feedback:
You don't get any, whether you get the job or not. I've been trying to get on the scheme for years - I've never been turned down for an interview, but failed the interview 4 times (two of them were normal 'panel' style). I never got feedback from the speed dating interviews even though I asked (pleaded) a couple of times. This is due to the "sheer number of candidates".
Not to blow my own trumpet but my skills, qualifications are more than adequate for the job. hence being accepted for the scheme finally (my 5th go...) but I've just not been able to get that across. I realise that being good at interviews is part of the game, but I know of more than one candidate who has been successful at the interview then made a hash of the job and/or quit etc. How did they make it through the interview?! (I'm not butthurt, honest).
A colleague of mine was an interviewer on the medphys team & told me that it's a scoring system (very much like the application stage) where they mark you X out of Y for communication, knowledge etc. I believe that these scores are then totted up, I assume in a spreadsheet. where the top scorers get their first choice etc. The problem at the moment is that there would be simply no meaningful feedback to give candidates except for their score. That's better than nothing though, I suppose.
I encourage anyone who is unhappy about the system to write a short note to the appropriate group/body. I'm not sure what that is just yet, but I plan on doing it too even though I'm now on the scheme. As it stands good candidates are failing but not being given the help to see how or why they failed. I don't think that's a great thing for the wider Healthcare Scientist field.
