Submissions should be sent via email to the address: {0xFACEB00C>>2 in decimal}@facebook.com

Since one can easily find the email with a quick Google search, I thought I’d show how to find it. The puzzle page is Unix-centric, so for this task I logged into an Ubuntu virtual machine that lives on my home network.

In ViM, here’s the simple program:

cute.  I have saved the file, and now I write a command to compile and execute the code.

And now we see the output of the email (below “[. . .]vim fbemail.c” and above “Press ENTER [. . .]“)

Yeah, no spoilers here… but if you can’t complete this task you won’t be able to do any of the others anyway.  No doubt the Facebook recruiters will judge me on my performance with these. This is going to be fun.
