I'm generally in agreement with the above answers.
A friend of mine was working in the back office of a recruiting agency and told me that they had on occasion hired people convicted of manslaughter, usually warehouse or other labor intensive roles. Presumably these were bar fights or other situations where things got out of hand, but she didn't know that many details.
Supposedly more than half of all resumes contain outright fabrications, often with respect to schooling. This link explores this in some detail. The article points out that when the employee is an insider in a public company, this is big trouble. In general, college degrees are easy to verify and there are many businesses that specialize in it. In some cases it's a bad idea for other reasons - some hiring managers may have less than glowing opinions of some advanced degrees, including MBAs.
This link relating to medical care debts relating to employment may be helpful.
One would expect a check on a driver's license to reveal a few tickets and perhaps a collision or two in the last five years. Employers would have reason to be concerned with multiple DWIs, an accident that involved a fatality in which there is little doubt you are at fault, or a ticket (along with jail time) for operation at 120 miles per hour. In short, 'no one is perfect', however certain markers for either substance abuse or callus disregard for the rules of the road and the safety of innocent bystanders would frighten a potential employer, along with pretty much anyone else.
There are plenty of people that have run up significant credit card debt. This is common for people in the 20s (including me in the late 1970s) and is often worse when people presume their future earnings can cover it. Some employers may be able to put this in context, others maybe not.
However, if you are being denied further credit and you are continually overrunning your limits, this means you still don't understand how to manage your finances. This would raise alarms. If you have $20,000 in total credit available, and you're paying down from $19,500, you're 'close' but on the right path. If you're showing repeated over-the-limit fees and everything is maxed out, then the employer could reasonably be concerned. You have, presumably, provided your address - if they find you're living in a luxury apartment (this is pretty easy to verify) it would confirm their fears. If you were living with your parents, it might mean something is going on you can't do much about. In short, a credit report probably doesn't mean much in a vacuum, but if other habits become evident on follow-up, it could scare them off.
There is another situation to consider - this is showing up in the business press right now about brokerages hiring people with experience in insider trading. Lets say that you misrepresent a fact or two on your resume, and you're confronted by your prospective employer when you're caught. If you're particularly slick, you might talk your way into the job anyway - whereupon you may discover the employer's morals are as questionable as yours. Like attracts like, and you may be ratting on your colleagues when the Feds crash the party.
