Refinery29 interview questions

First, there was an on-site interview where interviewer made sure I can code in Javascript. I passed and another interview was scheduled for another day, consisting of two parts: one doing coding puzzles, reviewing basic data structures and algorithms (this was very easy comparing to larger tech companies interviews), and two - working with a team member on a real task. Interviewer insisted that I use VIM for coding the real task because he was used to coding in it, even though I mentioned that I don't have much experience working in VIM.
