I’ve been through jury selection once, didn’t get picked. Honestly, it was as bad as everyone makes it out to be. Can be a bit boring at times so bring a book. And water. Definitely bring a water bottle. Really depends how quick they select people. They might have the whole jury picked before they even call you up. If you do get called up, you’ll be asked some basic questions like who you are and some questions about your opinions. Be honest, I didn’t feel like I was being pressured or anything. I was actually pretty surprised at how casual everyone was. The judge was friendly, took his time to listen to everyone’s answers. Bailiff seemed like a pretty chill guy. I was definitely expecting everything to be way more formal.
