App Samurai Software Engineer interview questions

After talking on the phone they send me a study case. I finish the case on time and send the company and then they arrange another interview with cto and others in bilkent office. They asked me lots of questions about my experience and i think i answer most of the question correctly and logically. But they dont send me any response or feedback about the position although I asked them via mail. The interview process absolutely time consuming for me.
