What resort depends what you're looking for. There are some tiny places and some huge places. Probably better off with mid to big as they have a lot more international people working.
The pay depends on what you do but don't expect to make a lot of loot. Probably will be around 8 an hour for a lifty most places.
Also job depends on the person. Some people like to work outside of the mountain and shred all day, some people like to teach, I like working in the park. It really depends on who you ask.
IT might not be a bad idea to find an area you like and apply to all the good resorts in that area to give yourself a better shot at getting a job at one. Not sure the visa situation but I've heard it can be a huge bitch. I don't think we have anything like the aussie/nz working holiday visas
