Punchkick Interactive Interactive Project Manager interview questions

I applied online and was contacted by HR. We sent up the interview for the following Thursday at 2 pm. On Tuesday at 2:05 pm, an HR representative emailed me to ask me if I was going to make it to the interview that day. He was replying to our chain of emails that stated Thursday at 2 pm. I replied and copied and pasted the date/time we agreed upon (even though it was directly below in the email he had written me) and asked him if he needed to move the interview. I did not receive a response so I showed up on Thursday at our scheduled time. I asked him about the confusion and he initially didn't seem to know what I was referring to, but then said "Oh, oh yeah that was my bad". We then went upstairs for the interview, where he asked me pretty basic questions about my experience and background. Then, to my surprise, mid-way through the interview he asked me what position I was interviewing for (huh?). He seemed nice and the conversation was not uneasy. He did keep asking me if I had any questions, which I asked him every question I could think of until I honestly had nothing left to ask. He then told me he would email a document with questions about my experience and to take the weekend to answer them. Friday came and went and I did not receive the document from him. I was planning on following up on Monday, but he did email them to me on Monday. The document contained 22 questions that needed to be answered in detail. I took two days to answer everything, type it out, and email the questions back to him. That was over a month ago and I still have not heard a word from him, even though I have followed up with him via email and telephone. I understand working in a more creative, lax environment, but a level of professionalism should still be maintained. Once someone interviews at a company, you should receive an email letting you know if the company is going with another candidate, you're not the right fit, etc. That's just professional courtesy. This company seems to be doing great work for major companies, so I sincerely hope that the two founders are just unaware of the situation. I also understand vetting personality from the beginning (which is clearly what the initial interview is for), but they are most likely missing out on some great employees due to lack of organization. Based on my experience, I would not be able to say anything good about the company due to the lack of respect of my time (it took hours to properly answer all of questions that were emailed to me), and the common/professional decency to let a candidate know that they were going with another candidate for the position.
