My only guess is that people working in recruitment have targets to hit in terms of number of calls to make each day and they'll try and hit that target anyway possible A guess that happens to be 100% accurate. Recruiters are targeted on a huge number of factors, primarily the number of jobs they fill obviously but also the number of new clients acquired, number of clients contacted, candidate contacts, client visits, etc. It's a long list.
