CFA Level I in December and CAIA Level I in September

Has anyone taken these exams in this overlapping order? I’m debating on taking the CAIA Level I on September 26th.

I’ve been studying for CFA Level I since May and scored a 79% on a Schweser Mock over the weekend. Lately I’ve been preparing for what will hopefully turn into an interview for an Analyst position in the Private Equity division of an Investment Management Company. In preparing I’ve been using the CAIA Level I Core Book and discovered yesterday that I’d already went through 20% of the Core Book in three days.

By the time I finish what I want to read ahead of the interview I’ll be through about 40% of the CAIA curriculum. I figured I should just press on and knock the rest of it out. Could anyone with experience shed some light on this and give their opinion?
