It was an interview for another job at AARP where I was already employed. AARP moves about as slowly as the gov. I had a screening interview with HR with your basic questions - why you want the job, why you want to make the move, reviewing your qualifications. Next an interview with the hiring manager who asked specifics about data analysis and wanted detailed responses proving that I could do advanced data analysis. Some behavioral interview questions like how do you deal with difficult people and give examples.
