I have and it was maybe fate that it happened. I have said elsewhere on the forums how it all came to be and it was through a friend and no application required. There were a few that knew me already but after the initial nerves it went really well and a great experience. My second job in a shop involved making an application in the usual way, and going through the interview process. I am now into my third job working in social care.
If you are presentable, have the qualifications, experience and give it a go who knows??
