Considering moving to Geneva. Any advice?

Hello,
As I am about to finish my Master's program in England (and having previously lived in Poland and the USA), I am considering Geneva as my possible next destination. I just wanted to ask how is it to live there. I know the quality of life is high, job prospects are good, but how is social life there? I am hoping that with so many international people everything from a planned event to a spontaneous night out is fun...? I am a very sociable person and being able to meet new people and hang out with them in some nice places is essential!
I would be very grateful for any opinion and advice. Thank you in advance!
