I applied online. I interviewed at Defence Science and Technology Laboratory (Portsmouth, South East England, England) in Jan 2015
Interview
Online application with generic personality and communication based questions along with a copy of your CV. About 8 weeks later I was offered an in person interview. Interview was conducted by two people, both of whom were very friendly. There were some technical questions and I was also asked to provide examples of various situations where I demonstrated various skills.
