I am very new to bonsai. My dad purchased one for him and I to work on together, after a couple failed attempts at growing them from seeds. We got a Mound Juniper, and I am not sure where to start in terms of pruning. I am looking for general advice with what I should do first. I also live in a very hot area so I am trying to find a spot outside that has morning sun and afternoon shade.

Thank you in advance!

wait a few years

Junipers need sun. You need to remember that the strength in Juniper is in the foliage, so don't go removing a huge amount of foliage, do not pinch the foliage, use shears when you do prune. Unless the soil is not permeating well there is no need for re potting. Use a balanced fertiliser through the spring and summer, and water when the soil is almost dry. Once you have the basics then you can think about styling what is a reasonable piece of material. I would suggest that you buy a book, there are many good ones, and also join a club. There is nothing better than being shown and helped with working on any tree. The courses on here are excellent, I have bought most of them and they are well worth it.
