I wouldn't consider someone an experienced or competent network administrator
unless they knew at least the basics of Sendmail.  Like it or not you 
ARE going
to encounter Sendmail 'in the field' and have to deal with it.  There are many
things, particularly in a directory enabled enviroment,  that Sendmail can do
and others like Postfix cannot.  <aside>Also, sendmail isn't really any harder
to configure than Postfix - all you do with other MTAs is skip the step of
turning your human readable configuration file into the actual configuation
that is used.  They just do it themselves whereas with Sendmail you use M4 to
do it.</aside>

I'd be stunned and very disappointed if you get to pick.  I'd suspect the
emphasis is on Sendmail,  as that is what you are most likely to find at large
sites.
