When you finish interviewing someone and they stick their hand out to say thank you. A word of professional advice you might not want to ignore them and walk away to talk with a candidate you clearly already know . I saw someone I will not say who for our NJ folks but not surprised I saw the same person do this twice on Saturday at Sen Booker / Menendez interviews. But not surprised as he always walks around like this. Sir these young men & women are all amazing even it they don't have 1600 SAT's like the ones you seem to gravitate too. So to those conducting these interviews. See the candidate and say hello with a smile, When you bring them back to the main room from the biggest interview of their lives thus far tell them it was great talking with you and good luck with everything you set your mind too. And the allow them to thank you back for your time.
