As there are no longer as many positions as there were 10 years ago and the authorities now have a great deal of experience, getting started is certainly no longer as easy. However, if you are interested and enthusiastic, it is definitely worth applying for an advertised position.
To increase your chances of being hired, your application should in any case make clear your own motivation for wanting to work for an authority. This separates the wheat from the chaff when applications are reviewed. In fact, getting started is the most difficult part, and you should prepare very thoroughly if you are invited to an interview. We are looking for colleagues with whom we can work closely for many years, and applicants should reflect the same desire.
