There were two types of interviews.

The first was an online interview. If you passed that, you would then report to Google itself for a face-to-face interview with Google's Chief Management Officer.

They would ask randomized questions, so it would be different for each person.

For me, they asked a general knowledge question: “You are going for golf and bring along 8 golf balls. One ball is slightly heavier, but you can’t tell. You have a balance beam but can only do 2 weighings. How do you find which is the heavier ball?”
