Having a Facebook post stating that you want a job will not help you. That will be vague and you will be picking the wrong channel to make such a request. Instead of utilizing Facebook, which calls attention to friends, it is better to center your job search on LinkedIn, which is solely professional and the social media channel of choice for professions like accounting, engineering, mining and business sales. If you do not have a LinkedIn account, create one and ensure to optimize it.
Simply having profiles on various social networks is inadequate to get a job. You have to vigilantly craft the messages you are sending. Blasting generic messages will not help you a bit. You will be speaking to no one in particular and misusing your time. The best way is to list down the people with contacts, knowledge and experience in the industry you are interested in. You could search keywords in Google+ or LinkedIn for positions or industries. After getting a list of contacts and prospects, you can have your message targeted to this group.
Note that if social networking succeeds, you might actually end up meeting those you are interacting with in person. Therefore, keep all your correspondences courteous and professional.
Remember, social media is only a way of engaging potential employers. You still require a resume in digital and printed format and should utilise recruitment agencies. And if you are lucky enough to get an interview, ensure you research the company’s structure, history, products and services in advance. This will make you more prepared, hence more confident.
