Any one out there work for a law firm in London?
Answers:
What side of London? You may be best off just applying to all the legal firms in your area. Also you could try Career Legal, who are a recruitment agency that specialise in recruiting in the legal sector from the top to the bottom. Also check out Reed.co.uk for any admin jobs.
I don't think you really need any legal experience to work in admin, although it does help. Just let your interviewer know why you are so keen to work in the legal sector and especially for their firm. You may want to do some work experience in a law firm first and then you will have the experience.
Good Luck!
