Hi Anna.  Thank your for your question!  I often here similar comments, regardless of where I have worked - in Japan, Singapore, Vietnam, Philippines, US, etc.  Our role as a headhunter (HH) is to fill the mandate given to us by our clients and to also provide our clients with talent insights and other value add services to assist them in meeting their current and future talent needs.  Many times, that means HHs have to search for very specific talent.  HH also have to realize that there is another side to the equation, and that is the candidate.  A good, professional HH should be very direct with candidates with what they are currently working on and whether or not they can assist a candidate with their current job search.  If not, then the HH's responsibility is to be candid and forthcoming so candidates can quickly seek other avenues, and to keep a good, mutually beneficial relationship, as that candidate could one day be very key to a certain search or even a client!  Try asking your collegues for referrals to good headhunters or see what people are saying about top headhunters on anpahbe!
