Joule Unlimited interview questions

The hiring process appears to be very unorganized. The process lasted several months. I was contacted by the company for the position. HR called me back over a week after asking for my availabilities to ask if I am interested in applying for the same position. The interview lasted almost 5 hours and I met just about everyone in the department. Each person was different, but overall the questions were about my work and how would I approach different situations. There was a slight feeling of nervousness by the staff about trying to commercialize, and different people seemed to have different ideas about how to do it. After the entire interview process I never received a call or email. Aside from the usual interview followup communication I called a week and a half later and was told that they no longer needed to hire as many people and wanted someone with more experience.
