The process took 1 day. I interviewed at Verizon in Nov 2011
Interview
Most of the time, 2 people are interviewing you and you will be asked a series of questions. Although it i snot required, it is best to answer in the "STAR" format: Situation Task Action and Result. For the result portion, it is good to explain the benefit to you personally as well as the company. There WILL be a question about a time when something went wrong (when you made a decision that ended up being wrong; you thought you could take care of something but should have involved someone else ect). The key here is to emphasize what you learned from the experience.
