You have to admire his honesty, if nothing else. :-)
Him: Hi, it’s Ben Dover here, this is just a courtesy call to find out a little about your skill set, so that I can help you get your next role.
Me: Cool, where’d you get my number?
Him: (Laughs) Oh don’t worry, it’s nothing sinister, it’s right here on your CV.
Me: So you have my CV in front of you?
Him: Sure do!
Me: And you’re phoning to find out about my skills?
Him: Sure am!
Me: Uh huh, so right under where it says “Contact Details”, where you got my phone number from, there’s a section titled “Skills”, that section pretty much details my, well… skills.
Him: Ah, yeah, no, totally read that, just it didn’t really mean that much to me so thought I’d give you a call.
Me: As a courtesy..?
Me: And you want to find me my next role?
Him: Yes, you’ve got it! That’s why I’m calling, as a courtesy…
Me: And terms like “Hadoop”, “Pig”, “hive” and “Python” don’t mean anything to you?
Him: Not a thing, that’s why I thought I’d call you.
Me: Yeah, I’m not sure you’re going to be able to help me, but thanks for your… courtesy.
