I applied online. I interviewed at Severn Trent (Birmingham, England) in Apr 2014
Interview
Fairly relaxed and friendly but challenging interview. Started with introductions and a chat about the CV, then a chance to talk about myself a bit. Main part of the interview was about 5-6 general questions...'give an example of a time when you did... etc', followed by one or two technical questions pertaining to the job. Overall it lasted about an hour. Make sure your answers are detailed they want to know how you think.
Interview questions [1]
Question 1
Give and example of a time when you encountered change in the workplace.
It was good, they asked a large variety of questions and I was given time to ask them questions too. The interview was also in a very friendly atmosphere that helped ease any prior stress.
