The Interview process started with an interview with an internal recruiter for the main business, in Richmond, VA. After a friendly discussion, I was referred to the west coast recruiter. That discussion resulted in 3 phone interviews over 4 weeks with in individual in a similar role to the one I was interviewing for, then the CIO who I would report to, and then the Director of HR. All these interviews went well, and ultimately, I was invited to fly to Pleasant Hill for face to face interview with 11 people, including the 3 that had interviewed me on the phone. All of this was very professional, in my opinion.
The only questionable experience was at the very end, when I asked a simple procedural question at the end, to the CIO, and was literally shoo'd away and told "I don't know, I don't deal with that stuff, ask someone else". What I had asked was how to get reimbursed for one particular expense, which is something I had not been informed of, prior.
That was the only time that I felt any concern for my fit in the organization.
