Prepare
Before filling out a job application, read it carefully. While most applications ask for the same basic information, such as your name, contact information, work history and responsibilities and references, they may vary in how they want the information presented. Read the instructions, and follow them to the letter. You should also have the information you'll need handy before you begin. Bring your driver's license, Social Security card, a copy of your resume and the contact information for your previous employers and references so you accurately input the information into the application.
Experience
While you might be able--or required--to submit a copy of your resume with the application, do not answer any of the questions on the application by writing "See Resume." Fill in the application using the same information that appears on your resume, and make sure that the information is consistent between the two. Most applications ask you to list your responsibilities at previous positions, so tailor your responses on the job application to the job you're seeking, and highlight the most relevant experience. If a particular question on the application doesn't apply to you, just write "N/A" or "Not applicable" to show the person processing your application that you read the question and didn't skip it by mistake.
Negative Information
When you're applying for a job, present yourself in the best light possible, so avoid including negative information on the application. Many applications ask you to detail why you left previous positions; if you were fired or laid off, write that the "job ended" and explain in further detail during the interview. However, always be truthful on your application. If the application asks for details about criminal convictions, for example, answer the questions truthfully and succinctly. If you fail to disclose a conviction, and it's discovered during a background check, you could lose the position because you lied.
Salary
Some job applications ask you to list your salary or wage requirements. Because some employers use this question as a screening tool to rule out applicants that want too much money, the best option is to indicate that you are open to negotiating pay. If that isn't an option, do some research to determine the average pay for that position in your area, and answer accordingly.
Proofread
Treat your job application as you would any other tool in your job search tool kit. If you're filling out the application by hand, write neatly in blue or black ink, and proofread handwritten or computer-based applications carefully before submitting. Make sure that you have answered all of the questions on the application, and sign and date the application if required.
