How's your German? I reckon it sounds like a good move, and the pay increase is pretty attractive, although not sure what the tax levels are in Austria?
My German is alright. I can understand 50-60% of the average German conversation, maybe 40-50 if we are talking strong Vienna dialect. Speaking I'm not so confident but I can express myself enough to get by.
I can go around a shop, restaurant menu, signs etc and know what most things mean.
Interestingly the job was posted in English (it's an international company, and an international role) and their website says that if the advert is in English then the expectation of the majority of the role and the recruitment process is also to be English.
The tax levels in Austria are a lot higher than here, although it is generally considered good value and a degree of healthcare is included. There is no council tax, and energy and water are significantly cheaper than the UK
Check out these tax breaks though, this is going to sting:
up to €11 000 - 0%
€11 000 – €18 000 - 25%
€18 000 – €31 000 - 35% (!!!!!)
€31 000 – €60 000 - 42%
€60 000 – €90 000 - 48%
€90 000 – €1 000 000 - 50%
over €1 000 000 - 55%
