As a +Yvette Mitchell
and +Quinn Conklin
mentioned, I'm looking for signs that the new hire is actively engaged in learning. They need to be open to new approaches and willing to ask questions when they don't understand; being open and acknowledging when they don't understand something is a sure way to keep my respect (they already had it before they started; I wouldn't have hired them otherwise.) Of course, if they come back to work the next day showing signs of working on whatever it was they didn't understand, my respect grows.
They also need to show signs of having the skills they said they had when they interviewed. I test for that as best I can, but I've had more than one hire whose technical skills weren't where I thought they needed to be. If that doesn't improve quickly, then it's not a good match and they need to go. Otherwise, as long as they're showing signs of moving through the learning curve, I'm happy.
Lying to me gets you fired. Being aggressive or uncivil with your coworkers gets you a warning, followed by termination. We have a culture of open attitudes, innovation and creativity here. I won't have that poisoned by someone who can't treat other people with the respect they all deserve.
