It is a multiple step interview, it will be around 3 meetings. They also do a ride along, so expect to spend a day with a rep. Be prepared to role play, and to provide specific experience, and be as detailed as possible.

Very easy. Relatively brief, over-the-phone conversation took place after a set of online "skill competency" tests. The particular position was considered temp-to-hire, which I believe is quite common with this company, however ultimately I did not accept the position.
