Call me old fashioned, but I believe that if you take time off from work to interview with a company, you deserve a response. Needless to say, MTV has different thoughts on the matter. After my interview, I followed up twice with no success. I think I speak for everyone when I say all it takes is one sentence: "Thank you for your time but, unfortunately, we decided to go with another candidate." That's it. This was my second unprofessional experience with MTV in the past 3 years.
Anyway, the process moved relatively quickly. Applied on a Monday, heard back on a Tuesday and interviewed (in person) on a Thursday. The interview was easy.
