I had that 155+ IQ and 800 SAT-M score, and honestly, the best thing it's done for me is take away my excuse for failing.
Once you get to a high enough intelligence that you can understand what the people around you are telling you and follow their train of thought, intelligence really doesn't matter all that much. Other characteristics like perseverance, social & communication skills, and emotional stability become dominant. There's nothing "magical" about getting an 800 SAT-M (or working at Google, for that matter), it's just that the effect of having a large body of knowledge that we spent thousands of hours acquiring to draw upon.
