Yes…it’s competitive to get in to. Especially if you are an Foundation Year 2 doctor and want to do it.
This can work in your favour though. As an FY2 there is only so much you could do by the time you get to applying. For example by the time you apply it would not be unheard of for you to not have done any membership exams. You may have done one radiology related audit, been to one course etc. The expectations are therefore different. You won’t be expected to have as much on your CV. But having said this you will be competing with other people who have lots of wonderful things on their CV and have done almost every job under the sun, so you’ll need to have something to be competitive and start working on your CV early!
Hopefully this will give you an idea about the numbers of applicants:
