Interviews are relatively easy, salaries have increased significantly in the past 2 years. You should be able to get 90K per annum with minimal effort, but that won't be enough to live like a low middle class German, if you plan to start a family. Housing is third-worldish, unless you can spend 2500-3000£ per month, weather is infernal and food has no flavour (unless you can afford to pay 2£ for an apple).
If you can get a visa to live in the EU, I'd consider Germany. If Brexit had one effect, it was to transform Berlin in a tech hub. It is much cheaper than London, salaries in tech are roughly the same and there's a large community of foreigners, so you don't need to learn German.
