Google Software Engineer(Internship) interview questions

They sent me a 90-minute coding sample and a survey. Coding sample was easy. After a while(more than 3 weeks), a recruiter reached me. We scheduled 2 consecutive phone interviews (15 minutes break). They were both technical but completely different. After these 2 interviews, I waited around 2 weeks to get to result. Then, they rejected. Don't know the rest.
