Do Interviewers Give Off Signs?

Dear Experts, When in an interview, are there any physical or verbal signs the interviewer can emit that will show what she/he is thinking? I want to know if there's anything I can look out for that will let me know how I'm doing. Here is how our CAREEREALISM-Approved Experts answered this question on Twitter:Q#414 Head nodding or a thoughtful smile is always a good sign an interviewer is listening / thinking. (@tmonhollon) Q#414 Interviewer's impressions are like porn-you know it when you see it! Focus on being in the moment. (@marysevinsky) Q#414 One sign: Interviewer talks too much about co; generally means they're trying to "sell you" on co/job. (@teenarose) Q#414 Try not to spend your time looking for signals. Instead, focus your energy on giving the best interview possible. (@gradversity) Q#414 A good clue is in the length of the interview itself. If I like someone, I keep them engaged / talking longer. (@EmilyBennington) Q#414 Interviewers R people too. Read them like U would any one else. Best "defense" is preparation. Be interesting & engaging. ( @DawnBugni) Q#414 Depends on recruiter, stage your in. Usually good signs: they lean 4ward, make eye contact, laugh w/ you. (@juliaerickson) Q#414 Some do and some don't. One of my HR coworkers can keep a straight face. I can't. :-) (@beneubanks) Our Twitter Advice Project (T.A.P.) is no longer an active campaign.
