I have found the carreers advice sections of university websites to be helpful in the past. Kent Uni was particularly good www.kent.ac.uk/careers and i didn't even go to that uni!
After much writing, re-writing and checking over (with the help of my former tutor and my manager) i put the application in the post. Now i just have to wait and see if i hear anything. This could be excrutiating as they state that they will only contact those who are short-listed, but don't give a date for this.
