Getting hired into law enforcement is not like applying to other jobs! It's complicated, time consuming and whether you realize it or not; it's up to you, to show an agency, why you deserve a chance to be called a Recruit Officer, Deputy or Trooper.
There are people who think this career would be fun, and they just want to give it a try. They won't be successful. Departments don't want someone who is just curious, and the hiring process is geared to screen them out.
You're reading this, which means you aren't lazy. You are looking for steps to be the best applicant you can, you're willing to educate yourself, do the work and understand what will be asked of you so can step-up and stand-out!
Other resources talk about one aspect of hiring, maybe just the written exam, or the oral board. This is the equivalent of trying to make a cake and only learning how to crack and egg and measure flour. It just won't work! You need to know all the different steps of making the batter, and what do if you need to substitute an ingredient or adjust the baking temperature or duration for higher elevations. The same goes for getting hired into law enforcement.
The things you read before didn't give you the full playbook, and without that you can't be successful!
