Google Intern interview questions

2 technical interview. No free talk, just questions and answers. Code on Google Doc and analyse the time and space usage with big O. The 2nd interviewer have serious accent and I misunderstood the question.

I got 2 phone interviews by an employee referral. Both last for about 45 minutes. The whole process took about 2 months. In the first 5 minutes, the interviews introduced themselves, their work and their team. They will ask you to talk about your project for the next 5-10 minutes. I had one coding problem of medium difficulty for the first interview, then one easy and one medium for the second. I passed the tech interview. However, it seems too late for project match. After 3 weeks' waiting, the recruiter told me the intern position are full.
