October 20th, 2009I had a preliminary interview with a woman at Facebook yesterday. We scheduled another interview for Thursday, which will have more technical kinds of questions. I asked her what i should be doing in the interum,and she suggested that I check out http://facebook.com/puzzles. The page had brushed past my radar in the past, but I didn’t give it a serious look until now. The page has a bunch of programming puzzles for anyone to do. Even the submission email address is a puzzle.
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.

Thanks. Didn’t use HEX much before, saved me some time.
