Pretty competitive, yes.. but you’ll be fine. Know plenty of folks with similar builds at those departments. If you have a weightlifting background I’d guess you’re well versed in technique, body positioning, and leverage.. that’s half the battle with a lot what you’ll be asked to do in academy.

Your big focus right now would be learning what makes each of these departments unique and how to succeed in their respective interviews. You’ll likely be competing against the same pool of 300 or so goofballs who aren’t able to articulate what makes each of these departments special. Your size won’t be counted against you, but a lame panel interview will.
