Apply online. You are asked a lot of questions, which they use to screen for experience. Then you are invited to interview. There are a series of questions asked, using the S.O.A.R. method. If you score in the top (however many minimum they need) they will then check your references. If those check out they will offer you the position, pending a background check which can be 7-60 days depending on your circumstances. Then they will offer a start date. The process can take months.
