There were in total of 5 rounds. Starting with recruiter round, and then followed by 4 other rounds with Product Managers at Google. Last round can be technical as well.
Recruiter sent over lots of helpful prep materials; between those and all the Googling I did ahead of time I felt well prepped. However the interviewer only asked one question (I was expecting approx 3) and it was very broad and hard to get what direction he wanted me to go in. I asked clarifying questions and was told to go in whatever direction I wanted to.

Question 1
Single question 45 minute interview- "CEO comes up to you and asks you to design the Google of Linkedin", what do you pitch him?
Product manager hiring. It took weeks, but it was full of learning. Infact, the HR was very supportive, wanted me to come to office and meet the team. The team was very helpful overall
