UScellular Purchasing Analyst interview questions

Interviewed with 3 different people... I can understand the first two. The first person was the Manager of the Purchasing department and the second person was the supervisor of that department, but the third person was not even a part of that department/team. He didn't have an idea what the day to day functions were for the purchasing department. I never received a phone call or e-mail regarding feedback, I assumed I didn't get the position because I never received follow up. After checking the "application status" tool on the employers website, it is still listed as "contact for the initial interview" which was listed before the actual in person interview. Employer should send feedback to all who have interviewed for an actual position.
