The panorama in Spain for many startups:
- 30k/year (minus all the taxes) ~21/23k/y - 28 days for holidays. - No health insurances (free health insurance on the country) - No conferences - No pluses.
Profitable companies: a bit more of money, but not that much: 35K/year.
About shares, as usual: the promise. some of them makes you sign something but to opt those you need to stay around 5 years, wait to be IPO or you can sell the opt to the company for a really stupid price.
With taxes you pay the pension, etc.
