Phone Interview with HR: Was very easy and casual. The HR lady just wants to know the basic things about you, your experiences, where do you see yourself in 2 years, do you want to be relocated, do you know how Google makes its profit, etc. The HR lady that interviewed me also explained Google's application process which includes 5 interviews that will likely take4 to 6 weeks.
1st Interview: The 1st interview was with 2 senior managers who you will be directly reporting to. The interview was done separately and was through video conferencing (even though the person was in the same building and floor as you). Questions were largely about explaining your background and then your professional experience as it relates to the position you are interviewing for.
After the 1st interview, I was told to wait for HR to get in touch and explain the next step. I am still waiting for HR to get back and have followed-up with them as well. But they only told me that they are still reviewing my application.
