5. Being Too Confident - Naturally you would think the more confident you are the more likely you'll get the job, right? Wrong. When I interview people, I look for nervousness in them. Why? Because it shows a sense of honesty, and honest people are who I want working for me.
4. Gum Chewing - Like standing in front of the judge in court, talking on the telephone, or making a speech, chewing gum in an interview is RUDE. Nobody wants to hear you smacking your chops while talking, popping your sentences, or watch you twirl the gum around your index. People actually do show up to interviews and do this. Maybe they forget? Whatever the case may be, make sure you spit yours out before you sit down.
3. Wearing Too Much Cologne or Perfume - Do we really have to go into detail about this one? What are you trying to cover up? You smelling like a french whore is not going to get you hired any faster. Just make sure you shower, soap and water will be just fine.
2. Having Trouble With Eye Contact - Never trust someone who can't look you in your eyes. If you're looking at the floor while talking to me, I'm going to think you have something to hide. Having little to no eye contact makes you look suspicious or guilty, and eventually I'm going to look at your resume to be as honest as you.
1. Sit Up Straight - Having correct posture is a must in any situation. Sitting like you have a spine full of jelly isn't going to make me feel confident enough to choose you to work for me. You might as well kick your feet up on the desk while your at it. Stand, walk and sit up straight. If you're too lazy to sit up straight, then you're too lazy to work for me.
Now smiling is another thing I didn't mention, but some people don't have great teeth. Smiling with your lips is always an option, just don't seem like your headed to the electric chair. You're at a job interview! You've made it this far, be a little excited!
