I got a bunch of PD friends and meet new officers everyday. It's a job that is different and new everyday. However the process to become a police officer, at least for the city of San Francisco, is not easy.
Prepare to wait 6 months after turning in your application. Then expect to meet up with close to 300 possible candidates for the same position you are applying for and expect an intense interview against 3 or more board members varying from representatives of the State Of California to Senior Supervisors in PD. The is also an obstacle course you must complete within a set time limit.
Get as much education as possible before joining. You need a strong college background to get noticed and stand out from the pack.
I know of people that applied and didn't make it. Good luck in that and I hope you join for the right reasons. However, also know that joining PD is not a simple or quick process.
