Meta Software Developer interview questions

First round interview at the facebook seattle office. The question was related to string parsing : basically given a set of key value pairs in some format, to print them according to another format. I did not understand the specifications clearly and probably should have spent more time doing that. Instead, I went through many iterations with the interviewer pointing out specific mistakes each time. My advice : the question may be very different from what you think it probably is, so spend enough time making sure you get it. Also, in case of this problem, it was algorithmically very simple, but you are bound to miss some cases and make certain mistakes. So, when you see a simple problem, try to look at the problem and your solution carefully for possible gotchas.

Got an email from Facebook that it sees my resume and wants to give me an interview. But first get a call from the recruiter to discuss about my intention. The phone lasted like 10~15 mins, just asking about my previous experience, graduation date, and my team choice. Then the 1st phone interview was scheduled. It is probably one of the hardest, thinking that they want to cut down as many people as possible. After that was the 2nd, then on-site. On-site, I met like 6 others Google Interns, and then we had a tour of the office, lunch, then 3 consecutive interviews. Then I got the offer like 3 days later (cuz I told them I had other deadlines, so they made it fast). They had a talk with one of my professor, who I wrote as the reference.
