Things are definitely changing in recruitment. The challenge for most companies who have regular vacancies is no longer filtering out volumes of applications which they receive, but more how to get enough relevant applications in the first place.
On the plus-side for recruiters, there are so many more options available to them now which were simply not available even 10 years ago. In response to the difficulties faced by many companies in resourcing new staff, countless new recruitment agencies and jobs websites are touting for the business of local employers.
You are unlikely to deal with all of the various service providers. However it is a good idea to give them a hearing and possibly even meet with a few carefully selected consultants and advertisers. Particularly where you have regular requirements. Spread the load across perhaps a number of specialists in various industry sectors and locations, both traditional media and internet sites. Savvy employers are now wheeling and dealing with a raft of outfits so as to ensure their needs are met whenever they come under pressure to get staff.
