Meta Software Developer interview questions

NDA

I forgot some of the coding problems, but here are what I can remember. 1. move all 0s to the front of an integer array. 2. given a target and a sorted array, find the highest value smaller than the target. 3. given a 0-1 matrix, find the largest graph that is 1-connected. 4. design a system that can quickly return public accounts' activity data. For example, how many persons like/comment Taylor Swift's status. 5. In culture fit round, was asked many questions about how and why did you make this decision, what would you do in this case. For example, why did you apply for grad school? why not go to industry after undergrad? Why did you choose your current company three years ago? Why did you move to this state? If at that time you also got an offer from FB, what would you do? Why FB?
