I’ve talked to hundreds of recruiters in the last 20 years and I find most of them don’t have a clue on the job requirements because they don’t understand them.
They have long shopping lists that most of the time no one fits exactly.
One afternoon a few years back, I sat down with the recruiters at a contract/hire recruiting firm to help them understand the work flow (as best I understood it) in IC design, so they could better understand the requirements they were seeing come through, and improve the referrals to their clients.
