Well, assuming you work in the NHS and are applying via NHS jobs, one of the best things about that website is, once you've applied for a job, your details can just sit there. So even if you don't get this job, if another suitable job comes up, all you really need to change, usually, is your supporting statement.
I actually ended up as a librarian because, after graduating, the only permanent job I could find was in the supplies department at our local health authority. (Great training, lovely colleagues, awful manager, ancient offices.) I'd been there for about a year when an information officer job came up in a different department. I and another colleague from Supplies both applied; we were both summarily rejected but were given totally different reasons. We heard on the grapevine afterwards that it had gone to the pre-selected internal candidate, but of course under HR rules the job had to be advertised.
It did, however, make me realise that the parts of my job I enjoyed were related to information work, and put me on the path, eventually, of becoming a librarian. Which, overall, has been a good career choice (mostly I've worked in the NHS and education with a bit of civil service and private company). I haven't always been called a librarian, either.
So, even if it's just experience, I think it's worth applying. Best of luck.
