Having no knowledge of either company beyond my own impressions I'd recon that Oracle is more "old-guard" employees in a much more collared shirt/blouse & khaki

Having no knowledge of either company beyond my own impressions I'd recon that Oracle is more "old-guard" employees in a much more collared shirt/blouse & khaki environment; while Pixar might lend to sneakers and t-shirts. Plus, again, having no knowledge, Oracle might have a section of people with Top Secret clearance, further lending to more faith into the 'establishment'.
