There were two phone interviews, first with a recruiter, who asked questions about CV, experience, motivation to work for Google. Second interview was similar but also entailed some questions about my knowledge of Google products. After a few weeks I was flown in to interview on site. This consisted of four 30 minute interviews. The questions pertained to my previous professional experience, included questions such as: tell us about a specific situation when you showed initiative/analytic skills/people skills, etc. Some questions pertained to my knowledge of Google product and how I would sell the product to a business owner. The three first face-to-face interviews were carried out by junior staff and the one was with the unit manager. Everybody seemed friendly and relaxed, as did the office culture. It is definitely relaxed, young and filled with energy.
