While reading typical recruitment stories, it becomes clear that over the process of recruitment, PNMs' perspectives regarding chapter ranking evolves. As you indicated, there is probably no one thread that identifies a recruitment story in which the PNM accepts a bid from her "last choice".
Yet as you read the threads and sort through the evolving patchwork quilt/kaleidescope of the process of recruitment, you'll see that PNM's may indeed have ended up choosing what was perhaps initially their "last choice".
Those posting recruitment stories may not specifically characterize their recruitment outcomes as their 'last choice' but there is ultimately a point in which the OP concludes that "X" chapter is now her first (and perhaps only) choice.
With all due respect to the OP "Wishful" - because I don't know she specifically would have characterized her house as her last choice - here is an example of one such evolving recruitment processes.

Indeed, there are more such stories out there - you just won't find them necessarily by the titles of the threads.
Please please please hang in there. You will NEVER regret it!
