Phone interview, then face to face interview with the hiring manager followed by several psychometric tests. Finally had an feedback interview with the hiring manager and a HR person. They analyzed my answers to the psychometric tests. I really waited a while between each steps so the interview process was quite long and stressful.

Three interviews. Mostly asked questions about the work conducted as well as some technical questions about general procurement processes. Was very conversational. Start to finish the process took 2 months mostly due to scheduling.
