I got a message from a company I would be interested interviewing with while my phone was off.  It started with a receptionist who said she is was calling from XYZ and please hold for the recruiter’s message.  Then, the recruiter gets cut off…wtf.  So, basically I have no idea if these stupid HR people think that they left a message or not.  How do I follow up to confirm?  I have no phone number.

This is why networking is important…limited HR mess ups.
