I applied online. The process took 2 months. I interviewed at Southern California Edison (Rosemead, CA) in May 2012
Interview
Edison uses the Tell us about a time multi-part interview question approach. My advice to external and internal candidates has always been to come prepared with 4-5 previous projects/situations that you have thought through in detail. Some positions do require assessment and testing, but not usually for office jobs.
Interview questions [1]
Question 1
Most of the questions are in the Tell us about a time multi-part format. Part 1: Describe the situation/project and your role in it. Part 2: Describe a challenge that existed (the interviewers will specify the challenge, it will usually be something like there was ambiguous direction, there were not enough resources, you had to work with difficult people. Part 3: Explain how you overcame the challenge. Part 4: What you learned/what you would do differently.
