Topic: The Club House / Answering interview questions

I recently got out of the Marines and I am wanting to start a carrer as a correctional officer. I have an interview at a prison next week. I would greatly appriciate some insight on what kind of questions I might be asked, and what kind of responses that I’m expected to give. I’m worried that I might come off sounding to ( yes sir, no sir). Military life is all that I have known for the past 4 years and I don’t want the interview board to think that I have no personality or that I am a little too agressive for the job.
