Banking, Medicine and Law are the main industries where salaries continue to grow with years in the industry.
My closest friend is an investment banker of 20+ years. He's worked/works at the top end in London with all the big name companies and has also worked in Aus. He told me that the newbies start anywhere between 100-200k. They are expected to do all sorts of hours, its their version of GA hard yards. He gave me a few scenarios ending them with "19-20 years of age, first job out of uni on 6 figures you do as your told or you're gone" "they know this is their lucky break and the rewards down he track are huge". Has some great stories of his career, very interesting but not my cup of tea. Incredibly cut throat.
