About one month after applying for the position online, I got an email from Google and an invitation for a phone interview. The first interview was mainly scanning my knowledge about Google and Adwords (i.e. "How would you sell Adwords for a small company?"), sales ("How could you improve your sales in X time by X%") and my interest towards the company and products ("Why sales? Why Google?"). The interviewer was very nice and encouraging throughout the whole interview, and at the end told me I had passed to the next level.
For the second (also by phone) interview with team manager, I got a very comprehensive package on how to prepare, what to take into consideration and where to find more information. I had also a case study to prepare. I was asked a lot of behavioural and personality questions ("How would you reach out a customer that has not been active for a long time?", "What is an accomplishment you are most proud of?") after the case study presentation. At the end I got a lot of time to ask questions and get insights, which was super nice and a great way to learn more about Google. The third interview was in Google Hangout with 3 different persons in different positions, and mainly again about Adwords, selling, behavioural questions and knowledge of Google overall. I felt that the interview went well, but got a call shortly after from HR saying that they had chosen someone else.
Overall, the interviews were a very positive experience. The HR was very supportive and kept me updated the whole time, and the interviewers were friendly yet professional, giving also opportunities to ask for more information and get insights.
