When it comes to your job interview, you want to leave it with nothing but positive energy. You want to leave the interviewer thinking that you will most certainly be a positive addition to his or her company. The last thing you want to do is to kill your chances with a simple mistake or two. While there are a number of ways to prepare for a successful interview, there are also a number of ways to quickly end your chances of getting hired. Below are some simple things to avoid during an interview:

Showing up late: This is not only rude, but it also reflects poorly on your work ethic. Do you routinely show up late? Are you someone who can't be counted on? Don't disqualify yourself before even meeting the interviewer.

Forgetting to turn your cell phone off (or keeping it on silent): Having a cell phone ring during an interview is not only disruptive - it's also disrespectful. While it may not be an automatic interview-killer, it certainly won't improve your chances.

Chewing gum: This looks/sounds unprofessional and tacky. No employer appreciates someone talking to them with a mouthful of gum. It's even worse if you're someone who chews loudly without even realizing.

Using I don't know as a response to questions: The purpose of an interview is to provide the interviewer with more information about you. The more you give them, the better.

Using slang or profanity: This is never a positive in the workplace. Speak professionally.

Bringing up personal problems: An interview is about the job in question and about your specific qualifications, not about your personal life. While you will almost always be asked to talk a little bit about yourself, try to keep the personal talk to a minimum. Certainly don't bring up any issues that will raise red flags.

These killers may seem a little obvious, but they happen all the time. Avoid these mistakes and you're already ahead of a large part of the competition.
