A school being tough to get into due to an abundance of population (too many applicants) means little. There has been not one significant person coming out of those institutions (compared to the many figures coming out of the US, despite a population 5x smaller). I would not hire Sundar as a junior engineer in my team. Of course, you might see something in Google's current leadership which I do not see. Time will tell how performant the company will be long term. Again, I believe skills that make one successful in consulting rarely translate to success in the engineering field.
