No, unfortunately, I can't give you a useful answer here. It seems that, in the first rounds of interviewing, you might not be interviewing for a specific position initially, rather, a function/role (for example, product management or software engineering).

In my case, I was clear that I was unable to relocate, which left only a specific position available as a possibility which was nearby. The reason I thought that specific position had technical responsibilities was by the description of said responsibilities in the job description as posted. Also, I was told that I was contacted by Google in large part because of my technical background, but during the interview, that background was not discussed or explored.

Sorry I couldn't be of more help!

In general, our product managers are technical -- almost all have a computer science degree, many have worked as engineers. When going through the initial interviews you are usually not interviewing for a particular position, but rather as a "generalist."

After the hiring committee has decided whether or not to hire you, your specific background will be matched with specific openings around Google. Naturally, some products require less technical expertise than others.
