What are all the languages that I should learn to apply for Google?
I personally say that you learn algorithms and data structures if you want to apply for Google as an intern or a Full time employee as a fresher. Google doesnt care about things like number of languages you are proficient at or number of languages you know. If you have good problem solving skills and coding skills in one language you are good to go. Once you get familiar with programming, its not difficult to learn a new programming language when required. Once you are familiar with algos and DS, try to learn about design process in software engineering domain. If you are applying for an FTE, some questions in the interview might come from this topic LinksInterview - Google Careers All the best :)
