In a bid to expand its reach and viewer ship. Rozee.pk has launched Facebook application.
This would be helpful as an employer if you advertise on Rozee.pk and have your own facebook page, and I think it would be far more productive than sending potential employees to rozee.pk landing page, where they might be wooed away by other opportunities.
That said however I think currently the job search our Graduates perform rarely emerges from facebook side, its usually directly on rozee.pk page because to be honest when you are out there looking for job you want to apply for all appropriate positions.
However for Universities and institutes it might be helpful in creating a facebook page experience where the students not only are aware of university/institute announcements but on the same page see jobs filtered to their relevance from the largest job portal.
If you are the owner of a page you can try out the application by following the instructions here
