560 euros ... u'd make more than I do, and i've been hired for almost a year. (provided that's your wage after taxation)
That 4 year binding clause is a bitch. If you could negocitate that out of the contract, take the job. Otherwise I'd keep looking.
Everything else is .... close to decent (for Bucharest), except that 4 year shit.
Get rid of that and you're golden.
Btw, this may sound unrealistic, but try finding something you enjoy doing. I don't hate my current job, but it's not in my area of expertise. Had to learn quite a bit of new things. I don't hate it, but I certainly don't like it. Also, if you get interwied by your future boss, try and figure out what kind of person he or she is. Having an understanding boss makes a difference when you're not employed where you'd want to be.
