If it's anything like Florida what you're going to go through is a selection process before you become an actual juror. First you'll go in and be put in a room with a bunch of other potential jurors for an hour+. Then officials come into the room and start calling out jurors for cases (around 30 people out of the potential 12 that will be selected to actually be a juror). Depending on how "lucky/unlucky" you are, depending on how you feel about jury duty, you have to stay in this room until you are called. Anyone not called by the afternoon/lunch time is sent home at that point.
If you are called into a group of 30, you are then taken to a court room and you meet the judge and lawyers. The judge/lawyers will give you "basics" about the case but they won't tell you specifics. The officers in the court room will also give you a few forms to find out about your job/your background in regards to your eligibility for jury duty (depending on your job/background, you could be determined ineligible/not a good jury pick) and then the lawyers will start asking you and the other potentials questions that relate to the case and how you feel about it. For example, one time I was on jury duty and it related to a man shooting a pit bull that attacked him. So the defense lawyer asked everyone how they feel about animals whereas the prosecutor asked how we felt about guns. Depending on how you answer these questions (ex: "I love dogs/I hate dogs") and how passionate you are with an answer will determine if you are picked. Since they are trying to give a "fair" trial, in this example, the "I love dog" potential jurors that were giving 5 minute long responses were the ones that were picked. If you're picked, you are on the case and have to keep going back to the court house. Otherwise if you aren't picked you go home.
