I'm a portfolio manager at a major hedge fund in Europe. I work hard, but I don't work long hours. On a typical day, I work for around eight hours and make time for walks and for listening to music.
Working for a fund is different to working for a bank. I have more autonomy. There are days when I finish early, or work from home. I have the choice when to load-up on risk and when to dial back down again, and this gives me a lot more freedom.
