Good or Bad Interview

Bad interview:
During a video I found online, I saw many things go wrong in the interview. First, they didn't introduce themselves or shake the interviewers hand right. Second, they kept biting on their nails/skin. It made them look unprofessional and gross. Third, they looked like they were dressed for the gym instead of an interview. They couldn't keep eye contact and kept looking down at the floor. 

Good interview:
After walking the bad interview, I watched a good interview. I must say it was a lot more better than the first one. First, they came ten minutes early to the interview to know they were ready. Second, should they had a firm handshake and gave direct eye contact.Third, Walked in with a positive attitude/mood with a big smile and good posture. Also, had a resume ready to hand in and looked nice. As you can tell this interview went much better than the first one I had watched.
