There was an initial phone screen with an HR rep, followed by a more extensive phone interview with the hiring manager. After that I was invited for a series of in-person interviews with five different people, including the hiring manager. I began the day by giving a PowerPoint presentation to all five interviewers, providing an overview of my resume, my vision for the role, and what I could bring to the role and the company. After that, I had a half hour 1:1 interview with each person. It was challenging but in a good way. Definitely gave me a sense of the company and the people I would be working with. Even though I did not get an offer, I still have a very positive opinion of Perrigo and respect for the work they do.
