Boyle Software interview questions

Contacted by a person of the company on Linkedin for an interview. Then got a visio interview with an HR. It was not so difficult and questions were open and absolutely not technical. I give a negative rating to this interview cause after the call, i never had news from them at all. Found this disrespectfull, i told them. People should be treated as people, not as pieces of meat.

Multilevel interview - first call was from HR that found me on LinkedIn, we discussed some very basic stuff to know each other, second was with lead developer, this one was toughest, we were talking about technical staff (see most difficult question below). Then two interviews with head of our company and PM from client company that we were working for.
