rebuilding staircase on concrete

Currently, the posts are sitting on concrete blocks and everything is shifting.

My understanding is that it would be best to put holes in the concrete and set the posts in there, but how deep should I dig?

You should dig down past whatever the frost line is for your area. Also need to have enough room to pour concrete into the hole after the post is set in. 4x4 post equals an 8 inch round hole. If the post is holding a deck up and the deck is over 3 feet above the concrete you need to go deeper than frost line and pour a concrete pad for the post to sit on and after that sets up then you place the post in the hole and concrete around the post.

Around here we don't usually embed wood into concrete. We use post anchors to keep the posts above grade. There are of course, a few exceptions.
