I worked in MaxFax for over 10 years.
I simply just wrote to all the hospitals I wanted to work in attaching my CV and a covering letter.
Lucky for me I was offered an interview at my first choice and got the job.
If they are a decent employer they will give you training and continue to offer training throughout the year (I never had to pay for any of mine).
It's a very rewarding job, it's very different from being in a practice which is what I wanted.
I've gone on to do other things within the dental industry that have been non clinical but found them just as rewarding and challenging.
Hope this helps
