I am a Level 3 Candidate, sitting in June.
Here is my suggestions:
1. Make sure you really want this, it is a total grind. I have passed both level 1 and 2 the first time, and I can say, even now this is not something for the faint of heart. The exams, you have to absolutely put in the time.
2. You are going to find that there is a wide variety of people taking the exam, very wide variety. Some are using it just to get a job, some are using it to advance in their job, and some are using it so they can move from back office to front office. The previous portfolio manager at the trading shop I was at, was a CFA charter holder and was very instrumental on me seeking it out.
3. Plan to not have a life for 6 months before every exam, most that I have talked with study more than the 300 hours suggested
4. I would not, I repeat would not suggest the exam unless you have a very clear path for why you are doing it, and plan on getting through it all.
5. I do know of several PE houses that have allot of CFA charter holders, some do not. Some require it. And I have seen several job posting, that have this "either a CPA, MBA, or CFA charter..." which tells you where people put it.
6. Level 2 is very quantitative, felt I had a leg up with a background in engineering, and felt FP&A sections were very straight forward. Each level is it's own beast.
7. <removed>
8. Glad I am almost to the finish line, it is sort of a rewarding beating.
9. I would read this book "Direct path to the CFA charter" if you are considering it, read the reddit threads, and go visit Analyst Forum.
