The CV is fine (I wouldn't put DuoLinguo as a proof of English fluency however, this is borderline) but the attitude is difficult. I'd prefer a guy who has fun

The CV is fine (I wouldn't put DuoLinguo as a proof of English fluency however, this is borderline) but the attitude is difficult. I'd prefer a guy who has fun solving hard problems, like say, "how do I convince people more senior than me to follow my advice", rather than someone saying "find me a cheap job where I don't have to deal with snobbish seniors". Find a way to build an inner child, something that makes you happy to learn in any condition even conflict. I can be insulted by a colleague and still find the experience an interesting challenge: how to make this moron either like me or do what I need him to do. I wouldn't quit, I wouldn't ask the company to fire him.
