Very long process wherein I had to make 4/5 phone calls and two tests over a period of about 3 to 4 weeks. Everything went great, always had positive feedback, even had informal coffee with "my future manager", but received an e-mail at the end that they wouldn't like to continue with me. This was a smack in the face based on all positive feedback and all the great stories they told me. I always assumed that I screwed it up on my last test, but I'm not sure as I all communication broke down after the "bad news" (not even a single reply on the question "what went wrong?" or "can I get feedback?"). I'd always admit my own mistakes and improve myself where possible but I didn't even know I needed an SQL interpreter, data analysis package (excel wasn't installed by default on my mac) or prior online marketing knowledge for the last test (which I had to arrange in the 1h test time frame). I was very hopeful and positive towards Quantcast during the whole process but the smack in the face at the hand was hard to digest.
