Google Software Engineer Internship interview questions

After being referred by a Google contact of one of my university professors, I was contacted by a Google recruiter to provide information about myself and schedule a date for the interview. I received a call from the interviewer at the scheduled time. I felt a bit intimidated by the interviewer during the phone interview.

Straightforward 2 45-min back-to-back phone interviews. Interviewed with one from Mountain View (HQ) and one from New York. They were friendly. Afterwards, the recruiter called me out of no where telling me they wouldn't be able to continue the process.
