I applied online. The process took 2 weeks. I interviewed at NHS (Cambridge, England) in Mar 2016
Interview
Mostly competency based questions, some technical questions, but all very standard and reasonable questions. It was in panel format, but people were very friendly and helpful. Be sure you do know the 6 c's and the NHS values. Make sure you do you background research by looking up panel members on linked in, and make sure you visit the NHS website ahead of interview
