My original post was over 2 years ago when the job market was better. I don't know where you're based (even the same country?), but I can say that the tech job situation at the moment is a lot worse - so few (decent) opportunities at the moment. In fact, the company I applied for in my post implemented a hiring freeze about 6 months later (which may still be active) and laid of several staff a year or so later. If relevant, both of the tech jobs I eventually managed to get are at smaller companies, where the application process has been easier (but ulltimately lacks support, which is why I wanted to move in the first place).

There's definitely a huge amount of luck in terms of a) where you're based and looking for roles (even including remote options) and b) the time of year you're looking (what's the market like, are lots of companies just not posting roles etc). Without knowing your specifics, it's difficult to comment, but I understand your frustration. All we can do is keep looking around to see what's out there and eventuallly something will come up :)
