They asked me about Data Structures, questions about django queries and 1 algorithm problem. The interviewer just copied the question from website and asked me. He didn't know the solution to it but he kept on it can be executed in O(n) time, I said how. He said I am just looking for a solution, denied to help me and later I asked again how will you do it O(n) time, he refused. He was a senior developer there and I didn't expect at that level you don't know how to take interview. For 1 question, he gave me a design problem - he though LLD is done before HLD. When I asked him product requirements, he said assume normal. He assumed I would have read it on internet. :D. Interviewer was - Mistaken - coming up with half cooked things - Just taking interview and sitting there on his laptop. Both of the guys who took interview were using laptop only while interview was going on. There was no interaction.
