Summarize the following:
A compliment from your interviewer is usually a good sign, especially if it pertains to something specific about your career experience or cover letter. Watch out for overly vague compliments like, “Well you're very well qualified for this position.”  While it's not likely to be fake or underhanded, this kind of praise is so general that it doesn't reflect much regarding the interviewer's attitude toward you. If an interviewer finds your answers to the warm-up questions smoothly handled and intriguing, he or she might shift into more complicated and specific questions to see how you acquit yourself. When fielding a tough question, don't rush to say the first thing you can think of.  Instead, take a few moments to contemplate your answer before responding.  Your interviewer will take this as a sign of sincerity and thoughtfulness, and your answer will benefit from the extra consideration. Although it can be tempting, try to not read too much into any single thing the interviewer says.  Pay more attention to the overall flow and feel of the interview, and not just to one or two seemingly negative or obscure phrases.  For example, just because the interviewer says, “I'm eager to speak with you more,” or, “Let me show you the office you'll be working in,” doesn't mean you're a shoo-in.  Often times these phrases are merely polite platitudes which your interviewer repeats to all candidates.  If the interviewer says something like, "Don't take it personally if you don't get this job," or, “We're interviewing many more candidates,” you should probably manage your expectations regarding this particular job.  Don't lose hope completely, but keep trudging along on the job trail and looking for more opportunities. Listen to the flow of conversation and watch how your interviewer responds to your answers.  If the interviewer interrupts your replies, it probably denotes boredom or lack of interest. Try making your responses more concise and see if your interviewer stops interrupting.  If that doesn't work, focus on remembering the questions you've been asked so you can work to improve them later. Often times, an interviewer's choice to guide the interview onto the personal plane indicates a strong interest.  This is because an interviewer is unlikely to spend valuable time on chatting with someone who is not considered a serious candidate. On the one hand, if your interview runs short, you're probably getting passed over.  On the other hand, if your interview goes long, it's a great sign that you've made a good impression and are a serious candidate for that prized position.

Summary:
Pay careful attention to compliments. Heed challenging questions as a good sign. Don't jump to conclusions. Pay attention to interruptions. Perk up if talk turns to chitchat. Take note of how much time your interview takes.
