Rebel.com Software Developer interview questions

Initially I was provided a coding test which requested that I build and submit a very simple web application given a set of requirements. After submission I was called in for an interview . The interview was just a chat about past experience, new technology and the role in question. During the interview I was told that I would be called back for a second round with the CEO. However, the rough timeline came and went... then a few more weeks went by. I sent a followup email and there was no response.
