Olympic lifters, we use the "high bar back squat" bar placed high on traps, feet are just outside shoulders, allowing hips to sit between the heels. Torso will be as vertical as possible. This allows full depth, limited only by your hamstrings hitting your calfs. Assuming you keep the weight on your heels, your knees are not valgus and your torso maintains a good posture, there is no damage to proper depth. This style of squatting is used for front squats in regards to stance, torso and depth.
These movements are sport specific but with targeting different muscle groups more than others, I am sure body builders will vary what they do.
Just don't be the guy thinking that reps at 405 while barely hitting parallel with the high bar, Olympic style squat is legit. Drop the weight and get low, or switch to a low bar powerlifting style.
