Octagon global recruiting ad appears at the end of LOST episode. Octagon global recruiting is an organization that is looking for volunteers to do scientif work to better the human condition. They are going to be in San Diego July 24-27, 2008. Octagon Global is seeking volunteers on behalf of the Dharma Initiative.
I think the Octagon Global ad was related to LOST in a way. Perhaps they are simply trying to draw attention to the upcoming drive? The ad was kind of cheesy though for a scientific kind of thing if you ask me.
These are unpaid positions and involve collective research with the aim to improving the human race through cutting edge, creative innovative research. The teams are led by leaders and experts in their respective fiels.
