Covalience Applications Developer interview questions

I had a negative experience during the interview. When I joined, the interviewer seemed disinterested and unprepared. The type of face which isn't friendly and you know the next minutes are going to waste. They didn't ask any questions about my qualifications or experience, and instead focused on asking overly difficult technical questions. I felt like I was being tested rather than interviewed. Just that I don't think that company is a good fit for me. The interview experience was a reflection of the company culture, and I don't think I would be happy working there.
