Flex Auto Deep Learning Engineer interview questions

Its a two step process. First one, it was a telephonic. second one was in-person. They asked about my work experience on phone call. So, i was asked to come to bangalore for in-person interview. I reached their office early for interview. seriously, office doesn't look good at all. It was full of dirt, Broken monitors. It almost looked like a mechanic shop. Anyway, then, interview started. They just asked me about my work experience and asked me to leave. Seriously, they did not even ask a question about ML. I felt as if they wanted to mock me calling over for a interview just to waste my time and money. Seriously dumb panel and their CTO, he's a real GEM! he doesn't even know basics. he's good at none. He just did a udacity nanodegree and feels like a MIT graduate
