Maybe this is specific to London. DD went travelling recently after a year of working in a field she has decided is not for her. She has a 1st from RG in History, lots of work experience, very personable and bright but isn't even getting interview invites. Same with some of her friends.
She's temping and living in London right now. Her CV has been checked externally (but she's great at that side of things anyway). It's been 3 months now and nothing. Finds probably 2/3 jobs a week to apply to.
