The new Jobster app on Facebook launched while I was on vacation, so I didn’t have a chance to blog about it earlier, an omission I will now address.

Technically, the Jobster Facebook app is an interesting example of a web services mashup that seamlessly combines three different technologies. 

• The companies and subscriptions in the Jobster Sourcing Tools application are exposed as REST resources using restlets, (implemented in J2EE, Spring, and Hibernate). 
• These resources are consumed by the consumer-oriented Jobster.com site (implemented in Rails)
• Jobster.com integrates this data with the Facebook sites using the Facebook API (implemented in PHP)

Below are screenshots of some of the key features of the Jobster Facebook app.

1,  The job search form searches millions of jobs from across the web, automatically suggesting jobs for you based work experience in your Facebook profile.

2. “Join Talent Networks” provides a categorized list of companies that have talent networks on Facebook, powered by Jobster. Facebook Users can get the inside scoop on jobs from these companies by subscribing to email updates.

3. The “Ask for advice” page slices your Facebook network by where they’ve worked, as a way to help you find career advice and connections when jobseeking.

3. The “Online Resume” page allows Facebook users to create a compelling online that showcases their skills and experiences, using their Facebook work and education history to get started easily.

It’s gratifying to note employers are reporting good growth of their talent networks on Facebooks in the initial weeks the application has been available; .

It’s pretty cool, give it a try or if you’re an employer, learn how to build your own talent network on Facebook using Jobster.
