The problem I find is lot testing companies in the UK as so small lots of recruiters post about the same job and after speaking to them find out I have already applied or know someone who works for the company. It fills a lot like you need some luck at the moment and its just not happening for me.
That's true of everywhere you go. Even regular IT jobs in the state I live in. I get 10 calls for one job posting, from 10 different companies. Bit of an annoyance really.
It becomes even more so, when you focus on the smaller subset of it, like security. Other parts of IT has better chances of being hired, but as was said to me recently, it's hard to sell security.
