Scytl Software Developer interview questions

I was contacted by them via linkedin. I did a preliminary interview, then a written assignment and then two more interviews at their offices. Overall I spent around 10hours of my time in this process. After the last interview they never called or write back despite my attempts to get some feedback. Funniest thing is that they reached me one year later and acted ofended when I told them I had no interest in working for such company.

The interview was composed by a set of stages: telephone screening interview, off-line technical exercise, pair programming exercise, and face to face RRHH interview. The whole process was more or less difficult. After that they make an offer.
