I'm often asked to give presentations to HR groups on trends in recruiting. Here is a video of the slide deck from my last presentation to the Human Resource Association of the National Capital Area (HRA-NCA).
The key takeaway is that Google search algorithms have a significant impact on the results you will receive from job postings, the visitors to job boards and LinkedIn are increasingly on mobile devices, and millions of job seekers are rating employers. All three factors require employers to adapt their recruiting strategies, or risk being left behind.
Fair warning, the purpose of the presentation was to highlight the trends, not to prescribe solutions, so there's no easy answer to be found in the last slide.
