I have been interviewed 3 times. In all these interviews I saw that the appearance and showing your interest for the job are crucial!! Working experience is very important too, like foreigner languages.
I have been searching different webs to a job advertisement in London and I found a lot of applies. The top sectors are: sales, accountancy and engineering. You can to choose it by two ways: by specialist or by location, and then you can see the salary, the location, something about job type and the date posted to send your résumé.
