How do I apply for a Federal job?

From USAJOBS Help

To apply for a job, there are four basic steps:

1. Create an account - Enter your profile information and create a resume. Please note that you do not need to create a “My Account” to search for jobs, but you must create an account to apply for jobs online.
2. Search jobs - Use basic search to enter in job and location keyword information from the USAJOBS home page or the advanced search function. Review the job opportunity announcements and note of those of interest. Carefully review the "Qualification and Evaluation" section to determine whether you will qualify for the position.
3. Apply for jobs - Carefully follow the instructions in the "How to Apply" section for each announcement. Submit any additional documentation to verify your qualifications such as transcripts, SF-50 Notification of Personnel Action, and/or Veterans’ Form DD-214.
4. Manage Your Career - Log into your account to obtain application status for positions for which you have applied. Contact the agency for specific follow-up questions or those related to the particular job. The agency contact information is listed on the right hand side of the announcement.
