You can definitely get a job in Google. Wherever you work you'll be required to have the basic computer knowledge. Even a person sitting at the reception or a data entry operator has to possess some computer knowledge but that's very basic. If you are not a computer engineer you can go for other jobs like managing accounts, becoming law experts, managers and so many other jobs. They won't require you to be an expert in computers. 

Good luck 

Hey!There

There is no need to have knowledge before class 12..But you have must have to interest in computer science engineering to bag a good job.Otherwise no chance of getting job in software company like GOOGLE, FLIPKART, FACEBOOK etc.There are large number of software company where you can target..

I hope this will help you.
