Meta Software Engineering interview questions

After a competition Facebook held on campus I was invited to interview on our university's campus. The interview consisted of a 45 minute 1-on-1 interview with an employee. It was the standard interview, a little chat about your resume/cv, a coding problem, then questions for the interviewer. There was nothing exceptionally hard about the interview. Know your algorithms and data structures. My question involved neither. I had a LOT of fun with the problem. My interviewer knew his stuff but refused to admit that Facebook uses Javascript.

Facebook came to our campus and I was pre-selected for an interview for their summer internships. They told me that it was going to be a 45 minutes long interview. The interviewer demonstrated very odd social skills, contrary to the fact that he worked for the major social networking company. Interviewer didn't even introduce himself, or look at my resume or ask how I am going. They instantly put me on the white board and asked me to write some code. I politely asked him whether he even looked at my resume. He mentioned that he didn't look at it, and he rather want me to focus on writing code on the board. At that point, I was a bit ticked off. So, I told him that I didn't want to work for a company where people are treated as coders, and not humans. Then, I just walked out on him. The entire experience lasted for 5 minutes. When I emailed the HR person expressing my disappointment, she defended the interviewer by saying that they were interviewing a lot of people and that's why they didn't have time to chit-chat with the interviewees.
