Google Software Engineer(Internship) interview questions

I had three round of interview each of 45minutes. They will give a problem and we have to write the code for it in a shared google doc. First explain your approach and if the interviewer is happy with the logic he will ask you to start coding. The questions were not very hard. Clearing data structures and algorithms concepts can get you through. Geeksforgeeks is great for DSA practice and concepts.
