I have opposite problem. Too many unrelated job offers with low salary, irrelevant tech stack or high tech debt. I hired secretary to do initial filtering. Final negotiation is always on you.
Anybody can get crap offers, the point of the agent is to get you good offers, because otherwise the agent doesn't get paid. My understanding of the system is that the final negotiation is on you in the film business too, but your agent is supposed to (be motivated to) help.
Has the secretary made a significant difference?
I get 1 goof offers out of 50 weekly. Secretary filters that, makes first contact, arranges details.... Money well spend.
