Avoid working with these guys. I was contacted by someone called Miles from there, who got me 2 interviews. Communication went downhill massively after the interview. I had to keep chasing him to find out what's going on and get some feedback. I gave an interview 3 weeks ago and yet not heard anything. When I do finally get hold of him he comes up with different reasons to why he didn't call me back. Very unprofessional.
