Goog Staff SW Engineer

Got a call from goog, this is about a staff engineer position. She said it will be an in person interview only, no tele screenings. 4-5 rounds of which two will be programming and the others about design and also about team management etc. To Googlers or others too who have faced these before... What all to expect the the rounds, details of problem types help, leet code levels help, example questions help...
