Speaking to a developer can be daunting for a recruiter. This is especially true for a junior recruiter, but self-confidence is not a surrogate for detailed knowledge even when you are talking about a veteran recruiter. There are plenty of recruiters who kid themselves into giving themselves more credit than they deserve for being “technical”, but there are ways you can size up if a veteran candidate “gets it” or if they are a hack.
Paper does more to slow the hiring process than any other element. Managers are harried to meet deadlines and ship product, but most often serve as the gate-keeper who must approve resumes for a candidate to move ahead in the hiring process. It doesn’t matter how you qualify IT candidates, whether it is coding exercises, technical exams or a Manager or Team Lead doing a phone screen. If this step is triggered by a manager “approving” a resume, that firm is hamstrung by a 900-degree feedback loop that will unavoidably drag out the hiring process.
