Labcorp Global Study Manager interview questions

Applied online and I got a phone interview with HR (about 30 mn.). Two weeks later I was invited for an interview with 2 hiring managers. Really pleasant atmosphere and I felt comfortable.

3 Steps: phone screening with US, face to face interview in Geneva office, phone interview with US managers. Long time with no feedback after the phone screen interview. Then I was asked into the office. 2 people were supposed to interview me in the Geneva office, of which 1 didn't turn up. Came back to me very quickly to arrange the 3rd and final interview by phone with the US. They told me I would hear within a a week. 1 month later I have heard nothing despite emailing and asking for feedback.
