the jobs link is interesting. Takes you to a functioning command line but has no other hints or instructions. An interesting gating function: those who don't know how to proceed further (or can't problem-solve sufficiently to find out) aren't likely to succeed in the role and can safely be excluded.
Might also have the added bonus of being safe from headhunter bot scrapers.
