Google Technical Program Manager interview questions

Initial round is the recruiter (over the phone: 30min) yet still very detailed surrounding project vs program management. Next round is a Program Manager (over the phone(45-60min) that the position reports into. He was also very detail oriented in regards specific project management areas, terms, behaviarol, situational, etc. Fairly standard but does much more of a deep dive and problems that arise with the answer you just gave. Next round was with a software engineer (on the phone 45-60min) who tests your coding knowledge while sharing a google doc where they can see you writing your code. From what he told me, everybody has to basically know code whether you use it or not because Google is a "coding culture". This makes sense and it is also used as a guage for problem solving.
