I used to work more with the public and, for the most part, enjoyed it. For the last 3 years I've been working in closed offices, security passes to get in, no public contact. And I don't like it. I really want to get back to talking to people but don't seem to be able to get the interviews. I may look over-qualified now.
Any tips re grovelling/getting across how keen I am? I write well I think, until it comes to cover letters where I fear I sound stilted. Overt enthusiasm & selling myself don't come naturally. Any key phrases to deploy or avoid?
