I've read interviews before where it was indicated they know nothing (and want to know nothing) until they walk through the doors to make their pitch. The extensive due diligence is done after the show, which is why deals struck on the show often fall through later on. For example, some of the companies that pitch indicate that they have patents, but of course the validity and defensibility of such patents is something that has to be researched, not something you can take their word for. So on the show they're like, "Do you have a patent?" and they reply, "Yes (or no)" and that's the end of that line of questioning because it has to be researched independently.
The reason they seem to get to the crux of the issues so quickly, is because like most reality shows, it is heavily edited. A five or ten minute segment on the show reflects sometimes hours of questioning and discussion. From what I understand they have VERY long days (much longer than 8 hours, more like 12-14 hours a day) so it's almost an endurance thing for the sharks, because they spend so much time fleshing out the issues (and why wouldn't they since they're investing real money).
Personally I love the show also. Also check out Dragon's Den, which has both a Canadian and a British version (same format though, 5 investors all competing), and more recently CNBC's show The Profit where Marcus Lemonis (who was on the Secret Millionaire) by himself goes to failing businesses and invests a hundred K or two and takes over management for a week to turn things around.
I love this new era of entrepreneurship-themed TV, beats the hell out of Survivor or Lost. =)
