I submitted an application and was invited for a brief 10-minute phone interview with the founder. It was just an initial screening asking about my background and my interest in the company. It sounded as though he wasn't really listening because his follow up questions negated what I had been saying. He told me that the next step was to set up an in person interview, which would likely happen at the end of the week. I sent him an email follow up giving him my availability, to which he never replied. A couple days later, I missed his phone call. Though I replied within 5 minutes, there was no answer. I left another follow up email, eager to set up an interview and he never responded again. I found this extremely unprofessional and disorganized.
