Perrigo QC Analyst interview questions

First interview was online, 20-30 minutes long. Heard back a few days later inviting me on-site for next interview. This consisted of a practical assessment, IT exercise and competency-based questions. I was on-site for 3 hours total, including for a tour of the lab. Everyone was friendly. Was told I'd hear back 2 days later, but never heard back. Disappointed. I followed up a week or so later with another email and never heard back, very rude and unprofessional.

After applying for the job it took over a month before getting an interview. It was a phone interview due to COVID. It was simply to get to know you as a person and determine whether personality would be a good fit. Was very short approximately 10 minute interview. There were about 5 people on the other end of the phone.
