What NOT to say in an interview!
1. "What does your company do?"
Do your homework and research the company. Ask questions that show you’re well informed and eager to work at the company, not those to which you should already know the answers, or that can be easily gleaned from the company’s website or annual report. Remember you must come across a well informed, pro-active (Make hint you have studied the website) and interested.

2. "My salary requirements are very flexible."
Salary questions are the most difficult ones in an interview. Especially if you don’t know the pay scalls of the company, and at the same time interviewers want to know what you’re willing to take. At the end it is a negotiation. Do you homework once again, come prepared for these kind of questions. Being able to answer well and confident (Without sounding arrogant) comes across as mature. You should be willing at least to give a range.

But don’t pretend to be flexible when you aren’t. If you’re worried that your salary requirements are too high for the job, you may need to do some serious thinking about how low you’re willing to go. Don’t sell yourself short, but ask yourself how much you honestly think you’re worth. Do research about what similar jobs pay and what salaries are like in the region. If a company comes back with too low an offer, you can always try and negotiate up.

3. "Don’t use Turbo language."
Friends and party talk will not be appreciated, so don’t speak it during a job interview. Using slang is a serious turnoff for interviewers. You may be articulate, intelligent, and confident.

4. "Your competitor offered me a $100,000 bonus."
Don’t lie! You’ll be found out, and you’ll regret it. Someday when you least expect it, someone somewhere will discover that you didn’t really increase sales by 999 percent in six months. Interviewers know you’ll probably exaggerate a little to sell yourself; but don’t cross the line between exaggeration and out-and-out lying.

5. "In five years, I see myself gone fishing for the entire day."
When interviewers ask you about long-term goals, they want an answer that relates to the company. Telling them that you really want to be living on a farm (unless you’re applying for an agricultural job) isn’t going to convince them that you’re an ambitious professional in your chosen field.

Even if you don’t plan to stick around long, say something that reflects a commitment to the position and the company. This may seem to contradict the previous exhortation about lying, but try to think of it as a rhetorical question. You might still be at the same company in five years, right?

6. “Sorry, I don’t know how to do that.”
Stress that you’re a fast learner and are excited about the possibility of acquiring new skills, rther than admitting that you don’t have a specific skill. Most companies would rather hire an enthusiastic, smart person who needs to be trained than someone who already has the required skills but isn’t as eager to learn.

7. “You see, I just went through a painful divorce. . . .”
Even if an interviewer starts getting personal, don’t follow suit. You may think you’re being open and honest, but you’re really just coming across as unprofessional, unfocused, and disrespectful. Keep it businesslike and polite.

8. “What can your company do for me?”
Interviewers hate arrogance and selfishness. They want to know why they should hire you. Stress the contributions you can make. Tell them about how your efforts helped previous employers. Don’t start asking about raises, bonuses, and promotions right away.

Remember, you’re the one being interviewed, and while you should use the opportunity to get your questions answered, you shouldn’t make it seem as if you’ll be doing them a favour if they hire you.

9. “I left my last job because my boss was a real jerk.”
Bad-mouthing your previous employer is extremely unprofessional and don’t forget it is a small world around us. Contacts stretch further then you think! Even if it is the truth, say that you left to enhance your career, look for more responsibility, you wanted greater opportunity for advancement, or you were just ready for a change.
