Google Senior Developer interview questions

It was long and after 2 phone interviews was schedules for an in person one. And they totally messed up on that last part. I was first contacted by a recruiter and informed them on the progress of my career and they said google would be certainly interested. What followed up was 2 phone interviews which I passed with flying colors.

Apply online and HR gets back to me with in one day. Interview is scheduled and pushed that out due to unavailability of interviewer. Finally date and time are set. Interviewer has strong accent and couldn't understand what he's asking most of the time. No introduction of who he is and what's his role in the team. Just start off with bunch of questions. Hear lot of keyboard strike noise. Interviewer must be typing during interview and also there is a lot of echo when ever interviewer puts phone on speaker. Interviewer has no knowledge about technology/role which is advertised.Not at all enjoy the interview.
