Is this a common experience?
It has been common experience these days. Even if you send your profile without asking any questions, still, don't expect any call/email from the consultant. A few years back, the consultants used to acknowledge the receipt of the resume and they used to keep the candidate updated. In fact, some were so good that they used to develop PR (as pointed out by Henry).
The consultant who referred me to my present company is still in touch and he sends greetings for festivals and keeps sending new openings available with them.
As already pointed out by someone, I think there are few good players in the market. Most of the current head hunters are very dumb. It might sound exaggerating as I say this. Recently, my friend got a call from a consultant. My friend asked him the job description but the consultant hardly had any idea. He always mentioned about the technologies but nothing about the JD. As my friend says, he kept repeating the statement that there is huge requirement from junior to very senior level positions. My friend wanted to know, for which position he is being considered but alas! the consultant had no idea.
Previously, head hunters used to read the resume and screen the candidates. Now its has become a dumb business where they appear to be paid for spamming and picking up 40 or 50 resumes by a lottery.
