I believe, that social media will getting more and more irrelevant, because people getting sick of this sensless throwing out infos, messages and contact attempts without focus and personal engagement. They will sooner or later love the old, good quality of personal human relations, Ear-to-Ear or Face-to-Face.
Since 2 years I see it also here in DACH area, that clients and candidates wanted to be called personally and not contacted via email or social media postings. Video calls are also fine, but some clients are unable to cope to work with that, so the good, old phone winns again, because its efficient and works from everywhere without WIFI. :-)
