Meta Software Developer interview questions

After the phone interview, I went onsite in Facebook Seattle. I had 4 interviews. One design, 2 coding, and 1 career/coding. I was not able to code properly in one interview even though I got an efficient solution in one go. So, I believe my chances of getting an offer is zero. Facebook is a pretty cool company to interview for. Thre recruiting team is excellent. I would definitely apply again in 6 months.
