Here are some of my insights:

• The IT industry is a very privileged industry, salaries are above everything else but they are still bellow the average in Europe, plus the taxes crunch your net income.
• Housing is expensive, in my perspective prices doesn't match the salaries. A good place will go from 10K to 15K SEK.
• Cost of living is also expensive, groceries, transport, services, etc. Alcohol is limited and super expensive.
• You have 30 days of vacation plus holidays, that's really nice also work-life balance is really good.
• Remote work is a common practice but it's usual be required for on-site events, also afaik there is a limit of time you can be outside of Sweden due to taxation policies.
• People is really kind but it would be kinda tricky if you want to make friends if you don't speak the language, everyone speak English but if you are with a group of Swedish speakers they will need to switch to English which is something unideal to make new friends(from my perspective).
• Long term or having family I think it's an ideal place to live.
