I applied through college or university. I interviewed at Google
Interview
I went to a career fair and was contacted by Google to set up a phone interview via email. They sent me information to open up a google doc so I could write code while they could view it simultaneously. I believe I talked to 2 different people during the process.
two 45 minutes on campus interview.
Basically talk about my resume for 2 or 3 minutes, and then begin the coding test.
The hiring process is: if you pass the first two 45 minutes on campus interview, recruiter from Google will probably select you. The probability depends on how much the manager thinks you fit for his/her group.
So there are some people that pass the two 45 minutes of interview but still does not get a intern at google.
