Hi Anoop, there isn’t any mantra to get placed into a specific organization that you want. However, you can surely try and for that what you can do is to understand the domain or role you want to or can take up in Google and once you and once you think you can be an asset to the organization in any way then you can apply for the job roles there.
It is difficult to get a job at Google because of their quality standards and the high number of applications they receive per year. However, several thousand people do get hired by Google each year, so it can be done! Write the perfect resume, networking takes you far, be persistent and nail the interview with good communication and problem solving skills.
