I agree that passing Level I really isn’t that meaningful. I was approached by McK some time ago for a BA position as well too, potentially in their corporate finance practice, since I come from a finance background and figured this would be the easiest way for me to leverage my existing skills and qualifications. I know a couple dozen people that are/were business analysts at McK, and the feedback that I got was that if you interview for CFP, they will definitely be interested in your financial knowledge. Passing a couple levels of CFA can help you with these interviews, but it’s not something that will really make a huge difference on your candidacy. Fact is, people who are looking to join McK as experienced hires tend to come from investment banking/equity research backgrounds so their knowledge of modeling and accounting will likely exceed that of someone who’s only taken exams, practically speaking. (again, as I always say, relevant work experience is most important) And then f you are applying for a junior role (like a first-year BA), they want to see your financial acumen but also your natural intellectual horsepower.
There is nothing in the CFA program that a McK consultant can’t understand, so if I were you, you can certainly mention how the CFA program has helped you out, but it certainly isn’t a differentiable skill unless you have the work experience to back it up…so just be careful that you don’t come across as thinking that passing one or two levels of CFA makes you analogous to someone with two years of a BB investment banking or equity research experience from a modeling or accounting perspective, because it won’t. Nevermind the fact that McK will also spend a lot more time focusing on what really makes you a stand-out candidate, what your leadership qualities are, etc….so when you take all that stuff into account, passing one or two levels of the CFA (or even all three) doesn’t really make you that “special” in and of itself.
