According to your style of recruiting, what role should hiring managers play in the recruitment process?

"Hiring managers have to become our best allies, we should talk about our expectations, our struggles and our wins so that we can understand each other in a deeper level. As a recruiter, I depend on them to see why I forwarded a candidate to the next step and also to catch something I may have missed. I say hiring managers must be involved from start to finish"

"As a recruiter, the hiring manager should know me enough to trust my ability to make the right selections, he or she should feel comfortable communicating with me if this is not occurring. In addition, the hiring manager should work with me to be available and support tight deadlines with short response time."
