Google Analyst interview questions

Three phone interviews, with HR and an analyst. The last of three was really hard and asked a questions for which you need to know a lot about google products.The last phone call was 45 minutes long and not really friendly or trying to make you confortable. They asked question about Youtube and Adwords and no personal or cv related questions.

Was hired through a consultancy for Google maps. Had relatively easy rounds for interview. One or two technical and final round was HR. Was asked simple and straight forward questions. Very formal and smooth interview process. Heard back within a month with a positive reply.
