STAR style questioning. (Situation, Task, Action you took, Results you achieved) Multiple people that interview you. First with recruiter on phone -- casual conversation to get to know you as well as some run-of-the mill interview questions. If you pass then an in person meeting is set up, usually with 2 or more people.

I was contacted by a recruiter over the phone and she explained the roles of the position and salary and such. Asked me if I was interested in what the job description entailed. So we scheduled a phone interview about a few days later. Basically, went like any other interview. History and background questions and then the star format of questions. I have no other experience in sales so those questions proved to be difficult.
