Nervousness
Another thing that the hiring person should be aware of is some people may be totally great at the job - but suck at interviews. I can't help it, I get very very nervous to the point I can hardly remember my name. Take this into account and try to make the person relax. Don't just stand there or sit there all high and mighty and gloat. I have heaps of experience and once in the zone I am fantastic in my field, but I just totally suck at interviews. I can't even do phone interviews very well and always think after the fact of good questions and good answers but never during an interview. Yet when I am working and under stress and the job needs doing, no matter what time day or night I am there and so logical and bang on. Check my references, they all say the same thing - I am an introverted thinker, but once in the zone I can teach the most confused person technology and make anyone feel comfortable around computers. But I am the biggest dork in the world in interviews.
