Clients don't understand passive candidates.
Lou Adler raises an important issue:
"Candidates who are passive tend to be less prepared during the first interview and can appear uninterested. This can turn off managers."
Man-o-manoschevitz, is that true. I, myself, have struggled to identify people who would be good for a job and then worked hard to entice them into taking a peek at it. And, then, my client wants to rule the candidate out because she didn't seem desperate for the job and didn't do much research on the company.
He didn't realize that the candidate wants him to sell her because when I called she wasn't looking for a job! Instead, the client wants me to go out and find someone else who is equally qualified and happily employed yet more enthusiastic.
