I think attractiveness is in the eye of the beholder. I look also for character compatibity because with some zodiacal signs I am absolutely incompatible. Pride comes that I never let someone walk on my toes, that I never let someone unknown's hand in my pocket but also that I have better results than my competitor (this of course is concerning the aspect of my professional life). When I meet someone, I generally judge on what she can say to me about countries she travelled, or what kind of movie she has seen or what kind of novels she has read, what are her passions and I also tend to ask if she is someone financially self-sufficient and/or independant.
Generally salary is always proportional to work experience hence why I always value people with a proven and real background but when some arrogant daddy's daughter with zero proven work experience has a better salary than you and is giving you orders, it is a niet for me. Thanksfully that never happened.
