I worked at Adecco USA full-time (More than 3 years)
I had two long term assignments from Adecco, each lasting 2 years, one of which led to an offer of permanent employment within the field of Psychiatry.
Weekly pay, option to be reassigned if the assignment didn't work out, gained more experience in a different field of medicine.
I applied online. The process took 1 day. I interviewed at Adecco USA (Evansville, IN (US)) in February 2011.
The people were great from the get go. I really appreciate the opportunity to work part-time and have a company that works with my schedule of my main employeer so well.
