Huh? What's this got to do with transparency? My company (MNC) has done it before. The reason for it is that we're doing the hiring on behalf of our contractors. e.g. I have a project contracted out, they need a support person - we hire on their behalf (interview, training, pay).
We also don't want to let our competitors know that we're hiring a whole bunch of this support level staff as it will let them have an idea of our activity here.
