Sorry it's turned out that way. Hope you find something soon, or without moving too far to find it.
I'm more annoyed at the way it was handled to be honest, the person I spoke to was the person who suggested changing the requirements in the first place and from their response today they had obviously changed their mind back some time ago, while I spent last week waiting and not applying for another job because I'd been given the impression I had a very good chance of getting this one.
This process is annoying but it is also helping me figure out more clearly which branch I'd like to aim for, and also helping my confidence because wherever I've gone, the clients and my peers have all been really positive about how I work and what I do, so I'm not being refused because I can't do the job, rather for logistical or administrative reasons I have no control over.
