Contacted HR, got scheduled three phone interviews back to back two days before Christmas. In all of the interviews, they introduced themselves briefly and started asking technical questions. There were two questions per interview and some follow-ups in situ. Due to NDA, I will not share the details, but they covered a lot of topics with three interviews: binary search, array, time complexity, recursion, tree, etc. You have to prepare many topics if you want to pass a Google interview. Interviewers were helpful in general and very patient. Still waiting for the result of the phone interview.

NDA.
