Meta Software Engineer interview questions

This is a 45 minutes video call interview, and there are two coding problems. You are asked to write code on a shared codepad.io link. You are not required (actually you are not able) to run the program, but you are required to walk through examples for the code that you wrote.

Recruiter reached out and scheduled a call. During this call, she did nothing but tell me how I was unfit for the position. I have no idea why she even called at this point. Facebook doesn't seem to be doing well and their recruiters act by far the worst out of those I've seen. Beware...something is wrong in this organization.
