Google Software Engineer Internship interview questions

I applied through a referral. I applied for the US and Europe at the same time period and they asked me to choose one of them. I had a recruiter, she called me many times (3 I believe), to check on me and clarify all the processes. I had two phone interviews back to back, and after a couple of weeks, they requested a third one. Then the recruiter said I was approved to go into the table where they take the final decision, and finally, I was told I was rejected.

The Interviewer insisted on asking me a question in a programming language I didn't learn yet, although I said my preferred language before. He was not nice at all
