Temptu interview questions

The interview process went over a month, included a phone interview, in-person w/brainstorm session, 2 follow up calls and 2 skype interviews. During the whole interview process they said they were extremely interested in me and yet after the final interview I didn't hear anything from them. I waited a week to contact them and they said they decided to restructure the position, couldn't they have realized that before they strung me along this whole time? Extremely unprofessional! To me, it sounds like they just wanted some free business advice otherwise they wouldn't have kept calling me. Also, they never made an attempt to contact me after the interview to let me know either way. I understand they are a family run business but if they want to be the leaders they aspire to be they need to have better recruitment practices to hire good talent. My advice, don't apply to this company and don't use their products.
