During Covid-19 lockdown, I was contacted by a recruiter from Google for a Software Engineer role based in India. I was given tons of resources by the recruiter to prepare for the interviews. I will try to share all possible resources, questions (hint), most important topics to study, platforms for practicing (daily questions and mock interviews), some tips, good blogs, and of course the mistakes that you should never make while preparing for big techs. Undoubtedly the technical interviews at Google are heavily based on DSA and it has got its own level of difficulty but I gave my best and went up to 3rd round after the written coding round. This drive and experience are really full of learning.
