I applied through a staffing agency. The process took 6 weeks. I interviewed at Diesel S.p.A. (New York, NY) in Feb 2015
Interview
Met with several people, sometimes in a panel. Called in again to meet with several more people. Eventually met with senior management. Everyone seemed very busy. Also seems like a lot of turnover in some departments here - there were multiple open positions in the department I was applying to and related departments. The office is really cool, but also seems kind of disorganized. The restrooms are gross and not clean.
The interview process was straightforward and efficient. There were three rounds in total, all completed within a four-week period. Overall, it was a fast and smooth experience with no complaints.
