Amazon Language Engineer interview questions

Had one screening with a member of the team, made it through that round and scheduled the main interview(5 back to back). They called me midway and said that another candidate gave the interview before me and accepted an offer so they won't be going forward with me anymore.

I applied online, had a talk with a recruiter and did one hour phone interview. My interviewer was very rude the whole time and she invited me another person (shadowing her) last minute. It made me more nervous and simply because her native language was on my resume, she wanted to conduct the interview in her mother tongue. Not sure if she was joking, but when I said no, she sounded really mean and disappointed.
