A recruiter contacted me through LinkedIn.

We set up a ~15-minute call with the recruiter a few days later.

During the call, the recruiter asked me about my current job and projects. Everything went well, and I was set up for a technical phone screening with one of their engineers.

We scheduled the phone screening for two weeks later.

Two weeks later, a Facebook engineer called me and asked about my current project, then jumped straight into the coding challenge. (See below to read about the challenge).

I became nervous and did not complete the challenge.

At the end, I got to ask the engineer a few questions about Facebook.

Two days later, I received a polite rejection email from the recruiter.

Given a multi-dimensional array representing a board, how would you traverse from one point to another?

The board has 1's and 0's; you can only traverse through the 0's.

Board = [ [0,0,0,0,0,1], [0,0,1,0,1,0], [0,0,1,0,1,0], [1,1,0,0,0,0], ]
