Research the Company and  Position
The more you know about the company and the job you are applying for, the better you will appear in the interview. An interviewer will thebe impressed by your interest and motivation, and you will be able to explain what you can do for the company. 
Find out as much key information as you can about the company, its products and its customers. If possible, talk to people who work at the company. There may be other sources of information on the Web, especially if the company is publicly traded.

Search for the following:

• Office locations 
• Products and services 
• Customers 
• Competitors 
• Philosophy 
• History 
• Recent news 
• Financial info, including salary and stock 

Practice your answers to Common Questions. Likewise, prepare a list of questions to ask the employer. Most interviews follow this pattern: First, you answer questions about your experience and qualifications, then you ask questions about the job. 
Rehearse your interview with a friend. You should be able to convey all pertinent information about yourself in 15 minutes. Tape yourself to check your diction, speed, and body language. 
Prepare your interview materials before you leave. Bring several copies of your resume, a list of references, and, if appropriate, any work samples. Make sure they are all up-to-date. 
Dress professionally and comfortably. You will be judged in some respects by what you wear. When in doubt, dress conservatively. 
For women: 
• A straight-forward business suit is best. 
• Wear sensible pumps. 
• Be moderate with make-up and perfume. 
• Wear simple jewelry. 
• Hair and fingernails should be well-groomed. 
For men: 
• A clean, ironed shirt and conservative tie are a must. 
• A simple jacket or business suit is a good idea as well. 
• Shoes should be polished. 
• Face should be clean-shaven; facial hair should be neatly trimmed. 
• Hair and fingernails should be well-groomed. 
• Use cologne or after-shave sparingly. 
• Bring pen and notepad to jot down any information you may need to remember (but don't take notes during the interview). 

"Tell me about yourself."
Make a short, organized statement of your education and professional achievements and professional goals. Then, briefly describe your qualifications for the job and the contributions you could make to the organization. 
"Why do you want to work here?" or "What about our company interests you?"
Few questions are more important than these, so it is important to answer them clearly and with enthusiasm. Show the interviewer your interest in the company. Share what you learned about the job, the company and the industry through your own research. Talk about how your professional skills will benefit the company. Unless you work in sales, your answer should never be simply: "money." The interviewer will wonder if you really care about the job.
"Why did you leave your last job?"
The interviewer may want to know if you had any problems on your last job. If you did not have any problems, simply give a reason, such as: relocated away from job; company went out of business; laid off; temporary job; no possibility of advancement; wanted a job better suited to your skills.
If you did have problems, be honest. Show that you can accept responsibility and learn from your mistakes. You should explain any problems you had (or still have) with an employer, but don't describe that employer in negative terms. Demonstrate that it was a learning experience that will not affect your future work.
"What are your best skills?"
If you have sufficiently researched the organization, you should be able to imagine what skills the company values. List them, then give examples where you have demonstrated these skills.
"What is your major weakness?"
Be positive; turn a weakness into a strength. For example, you might say: "I often worry too much over my work. Sometimes I work late to make sure the job is done well."
"Do you prefer to work by yourself or with others?"
The ideal answer is one of flexibility. However, be honest. Give examples describing how you have worked in both situations.
"What are your career goals?" or "What are your future plans?"
The interviewer wants to know if your plans and the company's goals are compatible. Let him know that you are ambitious enough to plan ahead. Talk about your desire to learn more and improve your performance, and be specific as possible about how you will meet the goals you have set for yourself.
"What are your hobbies?" and "Do you play any sports?"
The interviewer may be looking for evidence of your job skills outside of your professional experience. For example, hobbies such as chess or bridge demonstrate analytical skills. Reading, music, and painting are creative hobbies. Individual sports show determination and stamina, while group sport activities may indicate you are comfortable working as part of a team.
Also, the interviewer might simply be curious as to whether you have a life outside of work. Employees who have creative or athletic outlets for their stress are often healthier, happier and more productive.
"What salary are you expecting?"
You probably don't want to answer this one directly. Instead, deflect the question back to the interviewer by saying something like: "I don't know. What are you planning on paying the best candidate?" Let the employer make the first offer.
However, it is still important to know what the current salary range is for the profession. Find salary surveys at the library or on the Internet, and check the classifieds to see what comparable jobs in your area are paying. This information can help you negotiate compensation once the employer makes an offer.
"What have I forgotten to ask?"
Use this as a chance to summarize your good characteristics and attributes and how they may be used to benefit the organization. Convince the interviewer that you understand the job requirements and that you can succeed.
