Anybody know what qualifies as work experience for the CFA? Accounting, for example? Is it worth getting a CFA level 3 to become a card holder?
Accounting would be unlikely to qualify as acceptable CFA work experience. Are you asking whether it's worth it to become a CFA charterholder? That depends entirely on your career goals and has been discussed a lot here. Search for "CFA" - titles only - show results as threads.
if you are working in accounting, its better to get a CA, not an CFA (if you have to chose between the two)...but of course, if you have both CA & CFA then you'll be wealthy working as a Wall St Investment Banker, starting salary, $100,000.... lolz.
