1) Who cares?
Let me give you a piece of advice that will be helpful if you end up coming to Finland: Xenophobia doesn't distinguish whether you're Rajesh from India or Ernesto from El Salvador. Is there racism in Finland? Yes, absolutely. Is it to a level that you'll be afraid for your life? Absolutely not! Are you gonna see it from day to day? Very rarely. A drunken person may swear at you or call you some racial slur every now and then, but that's how drunks are in most of the world, so nothing exceptional. Maaaybe if you're biking in a white Finnish neighborhood (which is pretty much everywhere except dense population centres) you'll be given "the look".
Other than that, nothing major. You'll find your circles, people who find you interesting, fascinating, exotic Latino, you'll tell stories about your country and they'll be charmed, and those will be your friends. Beyond that, tune it out and you'll be happy.
2) Not straightforward. You'll need to get your credentials validated in Finland and take some steps (
more information on that here). Also, don't raise your hopes too high about learning the language. If you're working full time, it's gonna be difficult to learn, unless you're a language genius or very young (pre-highschool), or unemployed, ooor forced to do so by immersion in your work environment.
3) No, it's not. Once you're in Finland, it's quite easy to get everything setup, with exception for internet banking.
Every case is unique. You can't measure the result of your application based on arbitrary anecdotes online.
