Re: Interview follow-up note: First or last name usage?

During the interview, how did you address each other?  I would use that 
as a guide.  In interviews I try to stay very aware of calling the other 
person by the name they introduced themselves with, or the name with 
which they were introduced.  Usually if the other person is calling me 
by my first name, they expect the same treatment.  One of the pleasures 
of living in a flat caste system.

When I am the interviewer I try to stay aware of how the other person 
addresses me as well, using the same criteria.  I usually start by 
saying something like "Hi, I'm Jeff", and wait to hear how they 
introduce themselves.  Any follow-on communication should use the level 
of formality established in the interview.  My 2 cents, naturally.
