I don't think that had a large effect on my compensation, if any: I joined at L3, which is what most new grads are hired at, and my salary before Google was low enough that I don't think it pushed up my offer at all. I also didn't get offers from multiple places, which is the sort of thing that (a) results in higher offers and (b) is the sort of thing new grads usually do.

But ideally someone hired right out of school would be up for sharing their comp?
