one of the questions in the coding challenge was about file paths, and the big one during the phone interview was about hash tables. fair questions, not too difficult but challenging enough that you don't just breeze through them.

The second question was a bit confusing. Suppose you have a facebook API, which allows you to access all one's friends. Can you find if B is connect to A through friend's network? say A has friends (C,D,E) and C has friends(B,G). Now A is connected to B. I did the second one with a 7 layer for loop first, 'cause I was avoiding overloading the memory with too much data. However, the interviewer seems not to appreciate that. But I did answer the following up question wrong. He asked what is the big O for my code. A map search is N(nodes)+V(edge). I did not know that, I gave a answer of N, which is close but not correct.
