You have probably have had your final interview by now.  But you might want to assume, if you don't get this job, that you should prepare for "behavioral interviewing" which means you need to creat a bunch of SAR's (Story/Problem, your Action to solve the problem, the Results from your action).

The hardest problem you ever solved, the worst customer service problem you ever had, how you solved a major conflict between stakeholders, etc.  These need to be SAR's directly out of your experience, not your theory/training.
