I applied online. The process took 4 weeks. I interviewed at National Grid (Warwick, West Midlands, England) in Jul 2016
Interview
The interview was conducted in a room with 2 people interviewing. Quite formal with questions being read from pre-printed sheets covering different areas. When answering the questions both interviewers would frantically writing notes on what you are saying which I found a bit off putting and put me off my flow.
