dunno really.
if it was me, i'd be inclined to think that if i'd interviewed twice for similar roles with one organisation and not got them, that they had decided i didn't 'fit' and therefore wouldn't bother again.
although some people say that persisting with one organisation will pay off.
but having got this far, i suppose it's worth trying.
probably stating the bloody obvious, but have you done as much research as you can from what's in the public domain to get informed about what they do and how they do it?
the alternative would be to pad out the presentation with kitten pictures...
