Filling an application form plan: what is an application form?

Always Follow the Instructions:  Explicitly follow the instructions when completing both online and paper job applications. The slightest error could knock your application out of the running before an employer even gets a chance to look at it.
You might also want to check the company website or the fine print on the job application form, to verify you've followed the directions as instructed.
Review Before You Submit: Thoroughly read the instructions for applying for employment before you click the submit button (or hand in your application). Make sure every field is filled in. Some companies refuse to accept an incomplete application.
Notify Your References: Let your references know that you've listed them on your application so that they can expect an email or a call.
Be Prepared to Take a Test:  Some companies test applicants for employment in order to determine whether the candidate is a good match for the job. Companies who conduct pre-employment tests (such as talent assessments) are seeking applicants that match their precise hiring criteria. 
Being prepared for employment tests will help you respond better to employment-related questions. Some companies require drug tests for applicants seeking employment.

Review Sample Job Applications and Letters

Remember, the more prepared you are, the better your chances of getting hired. It pays to review sample job applications to give you an idea of what will be asked of you. It also pays to print out one or two application forms and complete them, so you know you have all the information needed to complete actual employment applications.
If you need to mail a job application or follow-up on an application you've submitted, take the time to review some sample job application letters for examples of what to write and how to follow up. 

Completing Application Forms

If you know what you're doing, completing an application form is a relatively straightforward process. But it's essential to spend time checking and perfecting your applications, as even a small mistake could result in rejection.
