Uber Software Engineer Internship interview questions

applied through my university, got back to me in two weeks with an on campus interview, had normal technical interview, question was hard and interviewer didn't seem to care, kept checking emails on his phone

The hiring manager notify me for an on campus interview three days before the interview. On the interviewing day, the interviewer introduce himself and start asking technical questions. You can write pseudocode in the interview. It is not a hard problem.
