When I recently asked my grandfather about his browser preference, he said Yahoo. I came to realize that he believes Yahoo IS the web; it's his start page on IE.
I think the role explanations should be clearly expressed in text on the site. I'm not saying the videos aren't helpful - they should just be included later in the navigation process.
Maybe I'll watch a video about Optiver when I've narrowed down a path, but initially I'm interested in the career and the roles associated with it.
I'd like to see figures like average salary, number of listings, and a succinct description of the role. Maybe even something in the same vein as the "Company Perks" on the individual company pages.
