Google Software Engineer(Internship) interview questions

submitted my resume online, then was given a coding challenge, followed by a survey, rejected a week after. The overall process took about two months. The coding challenge was fairly difficult. First question was a really obscure DP problem, second was fairly simple brute force

one online coding challenge, then fill out some questionnaire about where do you want to work/ what fields are you interested in, etc., and someone will schedule two back to back phone interviews for you
