I'm currently working as a industrial design & multimedia specialist
for a Fortune 500 technology & services company.  I enjoy the position
but want to expand my experience on both a client & international
level by becoming a brand strategy consultant for an international
brand consultancy (i.e. Interbrand, Landor, etc.).

     My current resume is set up mainly as for a multimedia
developer/designer position - which I feel doesn't exactly work for
consultant position.  Are there any resources, tips, templates that
exist out there that can tailor my experience and portfolio to better
match an international consultant position?

     Also, are there any interview tips & techniques that would help
when interviewing for that same position?

I think I know the answer to your problem.
