I just went through the same process - moving to London from New Zealand. I found that I had the most success when I directly applied to companies that I had a very very close fit with, rather than the more generic jobs. My feeling for more general jobs was that the companies weren't really interested in putting the time in if they couldn't meet me in person - but for jobs where I was a good fit they went out of their way to make it easy for me to interview.
I would recommend just picking a random company and putting some effort into an application for them, then rinse and repeat.
This has been my experience as well. I guess my initial hang up is some of the companies that I am interested in are so huge that my usual strategy of finding a hiring manager on linkedin is much more difficult. Where as when applying to a company of 500 employees, they probably only have a few hr people, vs XYZ fortune 100 company has potentially hundreds.
A very efficient type of 'nextgen' nuclear reactor that -once fueled - can potentially run, self-sustained, for decades without refueling or removing spent fuel. But it requires very advanced nuclear physics to design and maintain.
That's actually why I made it so nothing happens after you answer a question. Ideally you open a tab and every now and then you take a minute or so to think one over and answer.
Saving time is a good metric because it subsumes so much else.
1. Bugs = time 2. Features = time 3. Refactoring = time
