Google Software Engineer(Internship) interview questions

I applied online and the recruiter got back to me three month later to check my graduation date and visa status. After Screening, I got an email with two Coding Challenges and a snapshot survey. After two weeks, I got an email stating their willingness to move forward with my application and schedules two back to back 45-minute technical Interviews. In my first interview, the recruiter explained a game and asked me to code for Users Interface and I did well. My second Interview is on Array Concepts and easier than the first one but didn't get good feedback from the recruiter. Because he is expecting me to code the same method he has in mind though I ended up with the correct solution. Exactly after a week, I got a rejection email.
