Hey,

unlike other companies Google doesn't see your field of graduation, your cgpa or where you come from. Only your skill matters. All that you have to do is to prove your worth and your skill.

Any degree with enough knowledge in programming is fine with google in initial stages of selection. So, You can do CS engineering, EC Engineering.

To apply for a job

• go to official website of google
• search for job vacancy
• enter your data (resume) and work location
• find a job with skills relevant to you
• you will get the further process through google after successful application for job.

I Hope it helps

Good Luck
