I have been mailed by a recruiter who told me that a former colleague of mine gave him my contact details to serve as a reference. He asked to set up a phone call but never actually told me who the colleague was!
It's the first time that I've been asked to serve as reference for someone and I did not talk with anyone recently about being a reference. So I have no idea who we will be talking about.
When replying to suggest a time frame for the phone call, is it appropriate to ask the recruiter the name of the person who listed me as a reference?
Side note: I took into account the possibility that I misinterpret the mail and the recruiter wants to contact me with a job offer since I have been recommended by that unknown former colleague. However, since the mail subject says "Request for reference" I tend to think that they really are asking for a reference. On the other hand I also consider the possibility that they just use this as a door opener to get in touch about a job offer.
