QuinStreet Junior Account Manager interview questions

I had my first phone interview with the hiring manager who was nice but definitely seemed slightly disorganized and asked the same questions several times. After the initial phone interview, I had two more phone interviews with the managers whom if hired I would have been working with. Both managers were friendly and organized; the interviews lasted roughly 30 minutes and the questions were all pretty standard. Lastly I went on-site to have three more separate interviews. Over all people were generally friendly but it seemed as though all three people had been told of the interview that morning and there were a lot of awkward pauses as they scrambled to think of questions on the spot. I was told I would hear from the company in a week, but never received a phone call or interview. After 5 interviews, it is both disrespectful and unprofessional that QuinStreet never contacted me in regards to whether I had received the position or not.
