INSZoom.com Senior UI Developer interview questions

They scheduled the interview on Saturday 2PM. As the scheduled date can't be changed, I change my plans and attended the interview. Waited for 3 hours and in the end , they called and the interview started. Asked some old school aptitude questions and he said, I am a developer, so, I can't interview you, some one from qa team will conduct next round interview. I said, I am a developer. Then also, he repeated the same. Worst part is, I came out and checked with the hr. Then he was saying as it is late, we have to leave and someone will call you for next round of interview.. He said even without listening to what I said. Please don't think that people around are simply jobless and they can spent time for your fun purpose. Worst experience.
