WillowTree Intern - Hourly interview questions

I went through three rounds of interviews over the phone. They were brief, informational, and somewhat fun. They seemed very interested in me as a person and not just a potential employee. I had high hopes because every interview ended on a very positive note and I was quick to follow up, however instead of respectfully and professionally informing me that I had not gotten the position, they just stopped responding to my emails or calls. I would have rather been told that I did not get the position so I could confidently move on with my search.
