Ah, job interviews. A lot of people don’t know is that there’s an exact science behind job interviews. Each of the questions thrown at you has a rationale behind them. They’re not only designed to get more information about you, they’re also designed to see how you approach certain situations and how you can fit in an organization. Most experienced interviewers can spot a “winner” even if they’ve only gone a fourth of the designated questions. But with a lot of job applicants, they trip into these common pitfalls during their interviews. Here are 10 of the most common job interview mistakes that can cost you the job.

1. Being late - Two things - 1) first impressions last and 2) no one wants to be kept waiting. Being on time shows a lot about your time management skills.

2. Poor appearance - Not dressing up in proper business attire communicates sloppiness. Be sure to wear your clean and crisp business suit. Make sure you clean your shoes too. Look professional.

3. Poor track record - Not everyone can be won through flair. If you don’t have the credentials to back your self up, then expect some tough questions thrown at you.

4. Being a know-it-all - While you’d like to come out as a very knowledgeable person, don’t act as if you know everything. Keep a humble yet confident tone when answering questions.

5. Inability to accept criticism - You can’t please everybody and do expect some things to be pointed out even if you have a great resume and given a great interview. React positively and proactively. Thank the interviewer for those comments.

6. Unable to effectively communicate thoughts - An interview relies heavily on how well you communicate your thoughts. Practice in front of the mirror and try to create answers to the most common interview questions
.
7. Extreme nervousness/lack of self-confidence - Freezing up is the last thing you’d want to do. Look the interviewer straight in the eye and be forceful in your language.

8. Focusing too much on compensation packages - Sure you’re out for a job that pays. But remember that it is not the venue to negotiate the pay.

9. Trashing former employer - This is a test of you business ethics. Will you lowblow people just because you’re not affiliated with them anymore.

10. Doesn’t ask questions - Remember that interviews isn’t just a one-way street. They are exercises of two-way communication. So be sure to ask questions too.
