Turn to Social Media To Land The Perfect Position in 2013

Social media is a great tool for connecting with employers and top companies looking to recruit talent. Using social media, you can connect with employers and thought leaders in a way you never could have before. Your social media profiles on LinkedIn, Facebook, and Twitter can also work as an advertisement for your skills and abilities. So you should make sure to link your resume, video resume, and any relevant work samples to these online social profiles.

Leverage LinkedIn For Networking

LinkedInI prefer using LinkedIn to network and source jobs. It is a professional network with the expectation that people use it to network (e.g., build relationships, create relationships, and research people and roles).

Twitter For Finding Job Postings and Connecting

TwitterEmployers will post jobs and updates on Twitter, so it’s useful to follow to companies you are interested in joining. You can also follow the HR/hiring managers and engage with their tweets to help you build a relationship. You will generate the right attention if you publish interesting and relevant tweets, and if you re-tweet on a regular basis.
