I was contacted for interview by the HR who were terse and largely disinterested in individual candidates. The interview itself was not well managed. 50 candidates in one room in one day. The HR were not able to keep track of who should be called next. They had not been able to segregate people based on their technical profiles, so were asking each of them individually before sending them to the correct technical interviewer. The technical person had a clear idea about what he was looking for. Asked me about design concepts. I did not know design patterns at the time but he did not care. He still managed to test my design skills by making me write interfaces and class hierarchies. Asked me a few algorithmic questions, most of which I answered. He took time to ask me about my personal projects and showed genuine interest in all of them. He then gave me a form to fill, which was an indication that he had selected me. There were no other real rounds. Just a bogus HR interview after this, which seemed mostly a sanity check. It mostly just contained random generic questions about my existence so far. There was no discussion related to salary (probably needs to be initiated by candidates).
