I have found that it is very hard to get people to respond to you before you are in the United Kingdom. Sending off CVs with my Canadian address and phone number got very few replies, but since getting over here and sending out CVs with a
UK address and phone #, I've got more replies.
If possible, can you put a UK address and phone # on your CV? If so, I think this would help you out.
Like lynndyhop, I got a few bites in Canada, but things pretty much stalled until I got over to the UK and could do in person interviews. I am also in IT, and usually employers will fly you out for interviews, but people here weren't so interested in paying for me to fly over. Even when I offered to pay, things stalled. Now I am here, things have picked up.
Sadly, it's my experience that you probably need to be over here before you'll get many bites.
Cheers,
Greg
