I met a Wells Fargo IB recruiter who had a CFA (or at least completed level 1) and was working in TMT. I asked him about it and he said it definitely helped him better understand the financial statements within his own work.
I'm a college student, who's also considering the CFA, so I don't have first hand experience but I have spoken to a lot of IB recruiters. From what I gathered, the CFA shows that you're able to handle the quantitative aspects of IB work but it doesn't pull as much weight as a brand name undergrad/bschool would. In some cases, they might think you're not committed to IB since the CFA is more geared toward investment management.
And with consulting, the CFA is nice but also doesn't do too much with your chances of entry.
Now, please note that this was advice given to me. However, you're 33 so there is an age gap and experience gap. (which is already very rare for IB entrance) This could mean that the above advice is totally useless but I just wanted to share what I learned.
From your post, I can tell that you might be a little hesitant so I'm not sure if it is a good idea since the CFA does require devotion. (and I'm just going to assume it's been a while since you were in a study mode) But, if you have the time and the money then I would definitely go for it. Again, you have to compare the time studying the CFA (and this doesn't even mean that you're guaranteed to pass but let's just be optimistic) to what you otherwise would have done.
