Jennie,
i've heard a lot of radio shows over the years speaking about research showing repeatedly that we (most of us) make up our mind about someone in the first couple of seconds.
which really means we (most of us) don't even really consider what the person offers or says.
it also means that often, we don't have a chance as an applicant.
and this is on top of what sounds like her/their mind had likely pre-selected someone else.
on a more personal and opinionated note, i consider it plain rude not to shake hands in a professional greeting, and her saying nothing as a formal good-bye is equally rude.
crumbs...would you really want to work there if this is how "they" present?
