Easy. They will hire anyone. They do tell you that it is a difficult sale. Will send you home to think it over. When you call in a few days you will get the offer. They will offer $40,000...but that will change. Interview is very conversational. Mostly them showing off and bragging about their publications

Phone interview first, then asked to come in for a face to face interview where I was sold the position. I was also told that the position isn't for everybody, because of the close confines in which you must work along side of your teammates.
