I've tried CWJobs and LinkedIn. CWJobs seems to be returning the most results in my area. LinkedIn is suggesting roles too far for me to travel on a daily basis (I live in South Yorkshire and I'm getting roles in places like Birmingham and London), so I might have entered the wrong settings in there.

I'll keep trying, but one interviewer fed back to me that I was extremely anxious during the interview, even though I was trying to come across as relaxed.
