I had three interviews, all very pleasant and professional with a casual tone. The hiring manager explained in concise detail the role, and the unit work and dynamics. The second interview was with Scott - VP Sr Recruiter. I was pleasantly surprised by the casual format of the interview. The last interview was with the manager and a senior officer analyst. This time the questions were more technical. But with the same level of professionalism. The process was very smooth and timely. In less than three weeks a got an offer.
