Typically just hold at the bottom unless you are specifically doing a tempo squat (e.g. 3ct down, 3ct in the hole, 0ct up). A lot of raw powerlifters use it as a squat assistance/variation to build up leg strength, help stay tight in the hole, explosiveness, etc. Most common error is having a tiny bounce out of the hole. Just try to stand straight up without any bounce.
