"My Advice: politely ask for the shares outstanding, or for what percentage your share offer represents (then confirm the approximate shares outstanding). If the company won't provide you with this necessary information, it's unlikely they're going to be straight with you on other issues; go work somewhere else."
Not really, offering you a number of shares but refusing to tell you the number of shares outstanding is like offering to pay you 100,000 a year but not being willing to tell in which currency the 100,000 are. Might be in GBP (about 200k USD) might be in Yens (about 1000 USD)
