I recently got out of college and started looking for a new job online. I was surprised that there were ton of GIS job sites, but I have to say that one stood above the rest in terms of just being really nice and easy to use.
It doesn't have the most listings, but it does seem to have a lot that other sites seem to miss sometimes. Check it out and post a reply with your favorite job site if you know of any. I'm always interested in learning about new resources.
