Today I use something like:
"I was the winner of xxx translation contest. This means that I was evaluated by over 40 translators and, according to them, my translation deserved 1st place."
Does that sound arrogant? How can that be improved? Thank you!!

Well, there's nothing wrong with self-promotion. In fact, lack of self-promotion skills makes many people (particularly women) lose important opportunities at work. This is information from an HR specialist. The question isn't whether to do it or not, but HOW to do it :)
