Specifically? No, social media alone will not get you a job. It can't. You need to use as many avenues to connect and to engage with people as possible. Social media alone may not get you a job, but it can, if used strategically, get your experience, skill set, and accomplishments in front of the right people.
To land that dream job you need to connect with people: at some point this will mean talking to them on the phone or via video conferencing, or by meeting them in person. Social media might get you an introduction, but it will be that face to face meeting that will count. That, and your input. Your burning desire to get the job and your enthusiasm to contribute to the success of the company.
