how do fraternities give out bids?

I’m currently a high school senior. I’m kind of interested in rushing and was wondering on how the process works. I know that fraternities have different rush events. So i’ll list the questions I have down below

1. What are the types of questions fraternities ask during interviews?
2. How do you recieve a bid? Do they deliver to your dorm room or like give it to you in person?
3. Which fraternities haze? or what are the signs to look out for that a fraternity hazes or not?
4. Do fraternities at asu judge mostly on how you look?
