I have a question to all employers or people that do the interviews or hiring for their company?

What things when someone comes in the door to pick up a application do you look at or try to take note of? During the interview what things do you watch or keep an eye on the applicant for? For instance is it true that you look at the persons hair,body shape(fat or skinny),earings,nails,tattoos,what they are wearing,what kind of car they pulled up in,who they came with,how their handwriting looks on a application,how the person carries themselves or what things are definate if you will,turn offs to you as a future employer? On a resume what things might you see that will be like absolutely a no on getting hired? If you expect to gain new employees how do you expect them to have experience in a certain job or type of work if you will not hire them and give them a chance? I understand that there is not much time to fiddle faddle with people who simply do not want to work and
