I interviewed in a standard office with the LPN/hiring manager and the center manager. The LPN asked most of the questions and the center manager mainly listened. It was a very standard interview with basic interview questions. I did research on the company before I went to the interview and asked them questions about it (they really liked that). They talked about the process of donating plasma as I had zero experience in such a thing or even sticking needles! At the end of the interview they gave me a tour and told me that they would be making decisions by the end of the following week and they would contact me either way. They called me back exactly a week later.
