Well my situation is I was taken on as a band 4 engineer because I don't have the "relevant" qualifications (HNC Electronics or equivalent from the job description for band 5) and I have limited
experience, my 18 months NHS work was as a band 3 technician in community equipment. So I thought that's fair enough but when I start the job I find there are people on higher bands who don't have any qualifications and I'm the one who has to go to college on day release to do HNC Electronics which so far has only covered things I did 5 years ago.

I was under the impression that a qualification like a degree, say, was to show the level of competence you're able to work to, which should be equivalent to a certain number of years experience. Maybe I'm wrong? So I should be on a higher band to conclude.
