I cannot disclose how much we spend with them or the kind of cost savings that we see by using them. But I can tell you with certainty that we see a significant return on investment by using tools like LinkedIn and we see them from a way of being able to move processes faster, which obviously has a business impact and from a cost of doing business perspective. By spending money with organisations that enable us to connect with candidates effectively, we're not spending other money in other less effective ways and areas.

I wouldn't say so. Again, that savviness isn't coming through. What we're trying to do is getting people to come and talk to us. The required social media savviness depends on the role we're looking to fill.

We have a team who operate social media for us. We now have more than 11 million fans now on Facebook-so that team are incredibly social media savvy.

As for some of my colleagues, I've actually written their LinkedIn profiles for them and helped get them started and set up. They rarely look at LinkedIn but it helps me share and showcase the backgrounds of individuals who work for us. It works in a number of different ways.
