Meta Software Developer Intern interview questions

Facebook came to my school to conduct on-campus interviews for prospective interns. I was placed in the room with one of the engineers, where he asked me why I wanted to work for Facebook, gave me two technical programming questions, and allocated 5 minutes at the end to ask about his work and any questions I might have about the company.

Contacted by a recruiter and had an easy HR phone interview. The technical interviewer asked me to write a function that determines if a string is an palindrome. Wasn't terribly hard and I thought I found the solution, but wasn't given a second interview. Oh well...
