Not showing the relevant details of the cap table is ridiculous, companies that do this are banking on a pool of candidates that are either morons or don't care what they're paid.
Imagine the following situation: You're in a foreign market, and a vendor tries to sell you a fancy-looking machine. You know he's legally bound not to lie, so you ask what the machine is worth. He says "it's worth 2 billion Magic Moneys!!" but refuses to give you any information that would help you suss out whether that's 20 cents or 20 million dollars.
