Update the CV to tailor it to the description, and send it in.
Well, I`ve never heard of a CHange Manager being the same role as Project Manager. Change Management links in with Configuration Managerment/Config COntrol including release managerment, build management etc.
This is what I end up doing but its sad that the agents dont even know the basics of a role. No wonder that most actively encourage the clients to make the sector experience an essential requirement - it just makes the agents job easier because they have a smaller number of CVs to look at.
