An engineer needs to be involved in the initial phone screening. At my previous company we usually were able to find someone within a reasonable amount of time to fill an open position. One day, HR decided to seize control of the hiring process. They would conduct all of the resume and initial phone screening and then hand us a few "approved" resumes. It became impossible to find anyone after that.
