Hi
I wrote some things about the interview I had about a month ago with servisair in this thread:

This was at gatwick and for a dispatch position. I don't know how it would go for a co-ordinator position, I can imagine that it would be a little more in depth.
I gave the person doing the interview a quick call to get a little more info on what was required and also got a little repore going which helped me relax on interview day.
Incidently I saw the SVN in the crew room and thought about applying but I live to far away and can't afford to move yet. Just out of interest are you already a servisair employee.
Anyway hope that helps a little. Good luck.
