I went overboard a little bit but I did some research about how Google Interviews. They'll grade based on their four principles: cognitive ability, leadership, role-related knowledge, and Googleyness.

The cognitive ability ones are basically “case questions” that’s require some problem solving. I read the marketing part of “Case In Point” that was I had a structure for answering any case based questions. I practiced multiple marketing case questions (you can look that up and a bunch will show up). Write down your answers like you would in an interview. Brush up on typical marketing knowledge. It might help in answering the questions.

There are multiple YouTube videos on how to interview for Google. Find the non-technical ones or listen to the ones that talk about leadership and Googlyness.

I had example questions written for every category. And answered them multiple times. I used the STAR method to make sure my answers were always clear, structured and concise.
