Try The World interview questions

I had a trial assignment, then a phone interview, then a final in person interview. The phone screening asked what blogs I follow and what excited me about the company. The in person was more practically related.

I submitted my application on their website, got an email three days later (Friday) saying that the company wanted to move forward so I had to complete a case study. I sent an email to them saying thank you and I'll get it to them asap. The case study was due on Monday, I finished and emailed it back to them on Saturday and I waited. I waited and I waited. I never got a response saying "Hey, we got your email" and I sent it to them several days before the deadline so on Tuesday afternoon I contacted them to remind them/let them know I already sent the case study and I still didn't get a response. It's been nearly two weeks now. I wouldn't even mind a rejection email because at least that means you have the common courtesy to respond to me, but clearly Try the World doesn't have that. I spend all day completing this case study and I can't even get a single response in return? How can a company be so focused on communication and fail to communicate on a basic human level?
