“Further comments” during interview

Just finished a Hirevue today where the last question was something like "please add further comments you may have". I hadn't come across this one before, certainly not during a Hirevue. Nonetheless, I basically talked about how excited I was to be applying for the program, motivated to break into the industry, etc. General stuff. Realistically, what could be a good answer to this kind of a question? Thanks in advance.
