Ok. If that is what you meant. I thought you meant a recruiter as in a tech recruiter that finds candidates from different sources and then sets up the actual interview loop after a brief initial call that might involve a simple technical equestrian.

"Recruiter" usually refers to a person whose role is sourcing talent. Their responsibilities are more like identifying candidates, salesmanship toward the candidate, and minor filtering that doesn't require too much subject matter expertise (resume review, canned questions with correct/incorrect answers)

"Interviewer", by contrast, is much more often an actual practitioner whose main role is something else (it rarely makes sense to keep a stable of people around who are solid enough engineers to give interviews and not have them do actual engineering).
