Can future employers make decisions based on behavioral patterns from social media?

First of all this is not a research article and is merely based on my own thoughts. Facebook is the most popular and used social networking site right now and is likely to stay that way for the considerable future. Reading the 'data usage policy' on Facebook, we can see that they receive an enormous amount of information about us whenever we interact with Facebook. It can be when we look at another person's timeline, send or receive messages, like or comment on posts or topics, share quotes or links, search for friends or pages, click on advertisements, use the Facebook mobile application, or make purchases through Facebook. However, it’s not just what we post which is recorded, it’s when we post it and from where and what type of device we are interacting with. The information received by Facebook is fed back to us in ways that are quite noticeable, in the form of suggestions and local advertisements based on our interests; our interactions with which provide further feedback into the whole system, honing the specificity of the experience and enhancing the commercial value of the whole service. However, beyond these more common commercial considerations that most of us are accustomed to exposing ourselves to online, we use it for making and keeping in touch with friends and in that sense it is absolutely great. The portentous side is that people also use it for promoting themselves and boasting making us attention seekers. Several articles are available studying these aspects, egs.  http://www.sciencedirect.com/, http://arstechnica.com

Behavioral psychologists and social theorists can map the patterns in which how we interact with and on Facebook, building interesting behavioral patterns. How about if companies and corporations get these ‘analyzed behavioral patterns’ while they take a decision on employing a person, to understand whether that person can fit into a particular group or division. On one hand, these behavioral patterns will be genuine and totally under non stressed conditions, while such a test during an interview is biased due to the overall stress one faces during a job interview. Though I am sure there are algorithms to rule out that stress but it can vary quite a lot from person to person. The drawback is that one can deliberately prepare to be successful at such an interview. On the other hand, Facebook is not real life and it will be difficult to translate the social actions we make online to offline, mainly because, people could act differently on social media as it’s acceptable in that setting. In real life, do we interject into some random discussion we overhear or come across which interests us? Do we praise, like or comment on random things upfront to someone or something?  Are we self-promoters and attention-seeks in real life? Will this online behavioral pattern have any validity then? Let me leave this study open to the experts.
