Labcorp Accounts Receivable Specialist interview questions

Applied for several positions with the company, but only received a call about this one. Spoke with HR, who set up the interview/testing. Before interviewing, I was given an Excel and typing test. Once the tests were completed, I interviewd with the HR Rep, then with the hiring supervisor. The interview was very laid back and I was made to feel very comfortable by the interviewers. I was told that the decision would be made within a couple of weeks. I was called around 2 weeks later with an offer. The salary was not negotiable, even though I had years of experience. Since I was out of work, I accepted anyway.
