The recruiter:
"Hey, I saw your profile on LinkedIn and I felt you'd be perfect for a position I have for BLAH, a very established BLAHBITY BLAH, looking for someone like yourself who can do BLAH and BLAH. When are you available for a call?"
My response:
Hi, <Recruiter>. Thanks for reaching out! It sounds interesting but I'm going to need more info, can you kindly provide a salary range and location? Also, <additional question here>?
Thanks!
The Recruiter will answer one of two ways:
a) with the raw data
b) with an additional request for a phone conversation.
Folks, I can tell you one thing - b usually means the pay is below what I'm looking for, almost every time. So b I ignore and let them come begging (at least in this current climate where the market is strong).
