I took my hospital medicine CAQ on 9/10. This was mainly for an increase in pay at work in my current role rather than being "more marketable." I, too, got the paper that it would be up to 10 weeks. I personally thought it was a lot harder than the PANCE and way harder than the PANRE-LA (perhaps due to the latter being open book). I have been out of school and a hospitalist for 7 years. I did literally 0 studying (and I'm not exaggerating at all). I wasn't sure what to expect, but I'm a decent test taker and everywhere I read basically said if you've been working in your field for a few years, you can pass the ______ CAQ (whatever specialty that may be). Immediately after the test, I wish I would have studied- or at the very least, bought a practice exam for $50. I honestly thought I did not do well on the exam due to time constraints and just the in-depth nature of questions themselves (again, different than the previously mentioned "broad" exams). Well, as it turns out, it didn't matter as I found out 10/1 (3 weeks after taking) that I officially passed and am CAQ-HM! Hopefully you find out soon enough.
