I subscribe to the job listings rss feed from Joel on Software.  I subscribe to a lot of job feeds to see if there are any potential clients in them.  Tonight there was a job listing that intrigued me.  The listing did not list the name of the company.  Instead the applicant had to write some code to decipher what the company was.  I think that this was a brilliant way to attract talent.  I got curious and it sounded like fun so I went ahead and wrote the code even though I wasn't going to apply at all.

The listing said that you basically had to create a decryptor based on the ROT13 algorithm in order to get the company name.  I looked up the ROT13 algorithm in Wikipedia and it is basically a replacement algorithm where the first through thirteenth letters in the alphabet are replaced with their corresponding positions within the fourteenth through twenty-sixth positions and vice versa.  The listing said that you needed to figure this out:

string company = Rot13Encoder.Decrypt("perqvgfvtugf");

This is the class that I wrote to figure this out (click to enlarge):

I won't give away the name of the company but by the looks of their listing, it seems like a fun place to work.
