Hi,
I am an engineer that successfully switched to finance after passing CFA level 2(at the age of 28-29), but that's because there is friend that introduce me to the job. The first step is always hard as I know some of my friends that passed CFA level 3 still not able to secure a finance job and a graduate of Msc Finance from
SMU took a year before he finally found a job. He mentioned that most of the coursemates have already went back to China to find job because of the tough competition in SG
If you are mid 30 I would advice not to switch job as there is too much competition now in finance, unless you have a passion for finance or investing.
