Can I use Drupal to create Job Portal?

I know Drupal is a polymorphic monster, it can take many forms in any shape, you name it and Drupal has it!!!

But its a serious issue before you start working on some huge projects that can change with time, to select the right weapons before you go on a WAR ie. implement your project. I was much confused over building a Job Portal based on some CMS system, would that proove to be the right choice? And Drupal as we all know is the Best place to start with.

Im curious to know if anyone has done this before me? or even if its possible with Drupal? And yep there are some other projects I have inline a Yellow Pages portal and Matrimonial Portal. I would also like to know if all these Portals can be made in Drupal by using a mixture of CCK, Views and some more modules by some of the blessed authors who work very hard to make Drupal a Pioneer CMS system.
