That sucks. I've not worked in the BA, but can relate to a lot of this.

With respect to the interview process specifically, I've had an offer rate of maybe 30% over the course of my career (I'm in my 50s), and the process has been pretty easy. Sometimes a few whiteboard questions, but no take-home bullshit, etc. So, not too hard to find a job.

But on my last search, a few years ago, I experienced a lot of what you're seeing. Lengthy, unprofessional processes with maybe 15 companies. I finally ended up elsewhere, in an academic position. Pay is painfully low, but in pretty much every other respect one of the best jobs I ever had. And that's partly because the pay is low--my manager knows full well that I'm virtually irreplaceable, so I have a lot of power in the employment relationship.

Anyway, the thought there is that perhaps before leaving the technology field altogether, it might be enough to leave "Tech(TM)" (the part of tech that's huge in the BA and here on HN). There can be interesting things to do at rather boring sounding places.

Good luck!
