You must submit a separate application for each position to which you are interested in applying. Your application is evaluated on how well your training and experience match the particular position for which you are applying. Resumes are not accepted in lieu of the City of Brea employment application and responses such as "See Resume" will not be considered.
A "master" application might not do you justice in every case, and it may be to your benefit to tailor your application to highlight the skills you possess that are most suited to the position you are applying for. Once you have applied online, modify and resubmitting your application for another position is a simple procedure.
