Google Software Engineer(Internship) interview questions

There were two interview, back-to-back, each for 45-60 minutes. For each of interview, I had a short talk about my background, and the interviewer also talked about his/her job at Google for about 5-7 minutes. Then the question is introduced on a Google Doc. After discussing about solution, I started to write code and talked about time complexity as well as space complexity. Finally, the interviewers asked me whether I have questions about internship or Google.

Process took 3 weeks. Online assessment right after online application. Recruiter contacted me after a week and schedule 2 phone interviews with their engineers. There were 4 questions total and took about 2 hours.
