jack ass.

From what I understand , the real purpose behind screening is to make sure you are going to pay as expected? Or is it to determine if you are a gentleman or a jerk? Since it seems most screening focuses on employment, I dont see how they can judge your character from that alone?

seeing a chain-saw killer. Screening is for the protection of the provider, and to some extent, the client.

The number can be googled to confirm the business and when they call u it's to make sure u aren't LE.

you're right, they can't check all that with a call to your workplace for exapmle.  That's why most consider references from other reliable providers the best form of screening since it can address most those areas.

Make sure yes you're not a douche/jerk/crazy or the fuzz and to make sure he's reliable aka not a ncns.

All of those reasons, which makes it hard for someone like me who works for themselves from a home office. Who are they going to call to verify I am me?  I am a software engineer that works on contracts. I am new to this and anxiously trying, but I understand the reasons. As far as someone being a jerk, I treat everyone respectfully, but I bet these ladies have some crazy stories
