Ask HN: Is this interview street thing for real?

HN jobs has a link to the top to interviewstreet, which basically seems to be a broken version of codility. Does anybody know if this is just a paid link or if I should take this seriously?

1. The questions are incredibly basic 2. It seems to crash on the very first challenge I tried: Website's output 'TestCase #0 Status: Failed () line1 = input() File "", line 1 10 1 ^ SyntaxError: unexpected EOF while parsing Success" class="tooltip" /> Your output: Expected output: 0'

Additionally it has no contact-us section or anything.

I'd also like to ask, if this isn't paid for, why HN is soiling itself by promoting this link which is an apparent waste of my time (at least before it's release ready).
