I had 3 phone interviews in all. The first was a general interview about the hiring process and position with an HR coordinator. The second occurred about a week later. It was with an employee in the department of the position. I was then asked to write 3 essays - they gave me a choice of 5 prompts I think. Once I submitted that, I had another phone interview. The5 interviews were all pretty casual and conversational. A couple weeks after my third phone interview, they emailed me to tell me they wanted to fly me out to the Mountain View HQ for interviews. I did not receive any prep for these. They flew me out within a week, rented a car and booked a hotel room for the night. I think I had about 5 rounds of interviews with team members. Like the phone interviews, these were pretty conversational --- no quizzes or anything. A lot of convo about my past experiences and what I thought of the company, what I could offer, etc. Although I thought they went well, I was not offered a job.

It was in collaboration with my university so pretty smooth. The management was there in addition to the interviewing faculty. The questions were more relevant to the skillet and job experience but also participation within the university.
