sorority questions

I’ve got a couple questions about sorities rush and all that jazz

What is formal rush like what happens on each day, what are you supposed to wear, what should/ shouldn’t you do

I’m gonna major in engineering and I wanna be involved in clubs and maybe a club sport with adding being in a sorority on top of all that be too much

What do you love/ hate the most about being in a sorority

Are there any sororities that i should avoid

What is the general opinion of each sorority

Do people judge you for being in a sorority

If you have any additional tips/ info please let me know
Thanks for taking the time to answer my questions
