The London Business School Master in Finance is one of the most popular and well known MSF in London (and Europe). Bloomberg BusinessWeek has a chat with an admissions officer at LBS. It includes a range of topics, but there is some information on the MSF and placement/recruiting.

Here is a link to the LBS Chat transcripts.

LBS wants work experience for their MSF. Those without work experience are encouraged to apply to the Masters in Management.
