XYZ Batteries interview questions

I was recently interviewed at Google. The phone/1:1 interview went very well. I was able to answer all the questions, I also come from good university. I got an immediate response that I was not a fit. Sometimes I feel these positions don't exist and they just interview to get information, especially if you are from a competitor's employee.

Had to answer questions based on Math and General knowledge. It was simple and accuracy was important, not speed.
