Did a phone interview with the temp agency. A week or so later I was called to an in person interview on the Skillman campus. Arrived at Skillman, interviewed with my direct report 1:1 for about an hour which was a pretty positive experience, discussed my background and skills and how well I'd fit the position. After that I interviewed with the manager at the time for about 30mins 1:1 which was pretty similar. Not a very tense or tough interview, pretty relaxed. I don't think they were expecting much since I am only a temp. About 2weeks after I interviewed I got a call back extending an offer to me which I accepted. Note that I only got the offer because their lead candidate failed a background check.

Kelly Services called me after seeing my resume on a career site for a position with Microsoft as a contract employee. After a phone screenings with Kelly Services I was passed along 3 different job descriptions and asked for my preference. Later I had phone interviews with 2 hiring managers. Then I went to MSFT campus for 2, 1:1 interviews (consecutive, with different managers). I was given a response within 48 hours.
