Ok looks like if the url is referred from Hacker News, then they are displaying, {"is_fb_employee":"maybe soon? <a href="https://www.facebook.com/careers/department.php?dept=enginee..." rel="nofollow">https://www.facebook.com/careers/department.php?dept=enginee...</a>}<p>Even if you are logged out.<p>I am not an facebook employee so if i just paste the url in address bar and enter it, it shows: is_fb_employee: false with my UID.<p>If i logged out, it shows UID: 0 with is_fb_employee: false.<p>It's a nice idea to attract ppl from different site and based on the site domain, give them relevant career page url. (May be an intern project)<p>So for HN, it's engineering career page, if the referral site is relevant to some other domain (i.e. sales/marketing) then they will give <a href="http://www.facebook.com/careers/department.php?dept=sales" rel="nofollow">http://www.facebook.com/careers/department.php?dept=sales</a>.<p>Not sure how much data facebook have of other websites for categorizing majority of the websites in to different domain, but i feel Google can do much better with the same concept.
