Not exactly remote, but just want to ask if anyone has any experience living in London? I'm learning web dev at the moment and would want to move there to look for jobs. Hows the job market there now? Is it expensive to live there? Do IT jobs pay well there and are there many openings for software development there? Is the night life good? Any scenic spots to go to? How is the rent there? Is it easy to travel from there to places like France, Spain, Italy or other european countries?

I've never worked in another country before so how do I go about it? Should I get a tourist visa first then live in hostels/airbnb and hit the ground applying for jobs while I'm there? Do I need a working visa or be given one when I am employed? Sorry for the newbie questions, just trying to plan ahead.

Thanks.
