Google Applications Engineer interview questions

I applied for a role in Google and got a call from Google's staffing employee explaining about how Application Engineer role best fits my technical skills and experience. She explained about the role and asked me if I am interested in this role. I said yes and she asked a few question related to my experience and asked me to send my availability for technical interview which was telephonic interview with one of the Application Engineer. Technical Round was challenging. The duration of interview was 45 minutes and one need manage time while solving the coding problem. You need to explain what your approach is to solve the problem before solving the problem. It was a good experience overall.
