I would learn what ever secondary language is present in your area because that is a very good asset for the department and you may get additional pay for that skill. I would also emphasize "community policing" and working with the public during your interview and understanding that you will not be able to please everyone. You basically have to SELL yourself to the hiring board. Make a lists of assets you have as far as relating to the community and for the department. Tell them you want to make this a CAREER and you will not treat it like a JOB. This tells them you are looking long term and not treating them as a stepping stone to another state or federal occupation. Getting past the hiring process is only the first step. The police academy is a whole other monster so discipline yourself for a grueling schedule and major stresses because you will encounter some messed up situations in the field and this will prepare you for thinking on your feet.
