Google Site Reliability Engineer interview questions

Contacted me after finding my resume online. Typical interview for a tech company. The first call were some basic screening type questions. The second interview went more in depth. The questions weren't very difficult but the interviewer didn't seem to understand the material enough to judge my answers. Anything I would answer off script seem to throw him off. Gave up about half way through.

I got a phone call from a Google hiring employee. In this call, I sad I would like to take part in the hiring process. After that, she sended me an email with the job description and a little self-evaulation test.
