I did free work for my former company before I get in there as a full-timer, (hoping that I can get a job) did 30 pages of translation for their tech/general side of white paper. Thing is. they don't appreciate (if they are a startup worse) and also they think; Start-ups, getting a "SUPPORT" from people is their rightful "Right". Not every person feel appreciations for our work and time. This is a sad fact.
