Some recruiters can truly get on your nerves. I once applied to Expedia; the recruiter once called and asked me what's an 'Epic' (from Agile Methodology). That was my first call after email communication. I expected the HR guy to ask questions about my experience and setup an interview time with an engineer. I just didn't get why asking for a definition of keywords from the Agile Method was the first step in their interviewing process at all!
