I got referred by my friend who worked in google and was contacted by the HR after a few days. The first interview is a phone call interview by the HR. She just briefly introduced the interview process and asked the questions about the resume and Google Adwords.

Got reached out to by a recruiter. Passed the screening call last week. rd1 interview is coming up this week (11 days after). Apparently only 2 rds of interviews this process. Though the 2nd interview consists of 2 45min interviews in one.
