Labcorp Study Technician interview questions

It started off with a phone screening, and then I immediately scheduled an in-person interview in Madison, WI. I interviewed with two different people (separately). Mostly behavioral questions, nothing too farfetched. A few days later I was asked to submit my W2's and paystub along with a copy of my diploma. They said this would take 2-4 weeks, but it's been over 5 and they still haven't offered me anything. Anytime I email the recruiter to ask for an update on my background check, she promises to have an update for me the next day, but never follows through.

I received an email requesting I schedule a phone interview. The phone interview lasted 15 minutes and I was asked about my education background, work history, and research experience. I was also asked questions about working with animal models in research, whether I had any experience with animals, and whether I owned any pets. The interviewer was very nice and was typing out my responses as I was giving them.
