I was contacted by the recruiter after I applied online. I was asked to take a 30min online interview. It had analytical questions, basic CS thread related questions and coding questions.

First round was online assessment on Hackerrank. It had 10 MCQ's and 1 programming question and 1 code debugging question. The level of questions was moderate. Next round was the phone interview with some code fragment provided in the mail. The phone interview was weirdest of its kind. The interviewer was in a completely different world and asking some memory management question on top of the code fragment. He was imagining things and writing it down while making it difficult for me to understand what he wanted and what he was trying to explain. I believe he himself was not clear of his requirements. When asked about the product he was working on, the answer was in a similarly confusing manner.
