There are no guarantees. It's that simple. You can be knowledgeable about your goals and what you can bring to the role, but that's about it. You do understand that you won't find out where you are placed until AFTER you arrive for check-in, yes? For instance, during my interview, I was asked my favorite park. I said DAK and there was a small conversation about why. Happily, I was placed in DAK (merchandise), but I was given NO chance to give a preference to my location within the park. I also believe the interviewers to be pretty savvy and onto people who try to use buzzwords or "tags", as you call them. Also, if you only check one role, that's not going to look good for your desire to work for the Company.
