Initial interview at the university. Very positive experience. General interview questions and some questions about adwords. Then 3 onsite interviews with team members of the position in question. Different types of questions, scenario questions, usual interview questions, questions about adwords. Google way of interview questions are behavioural type, which is the best type of questions in my opinion. Overall very positive experience. After the onsite interviews, there was a stage that certain committees should approve the application in order to receive an offer. Most nervous phase for me was this last one.
You should be prepared for the interviews. Recruiter assisted me a lot during the whole process and was very nice, kept me updated at every step. Also Google likes to keep the process as fast as possible, which is also a very good thing.
