I am going into my third season here, and I feel that I am now qualified to tell you some things you need to know before applying at Blue Mountain.
1: It's pretty easy work. Most of the jobs you may be doing are very easy. Some management jobs may be a bit more difficult, but a "standard" position, (for example Rental Attendant, Lodge Attendant, Ski School Instructor) it is quite easy. It can also be quite fun.
2: Perks. As an employee, there are many perks. You get to ski for free (free rentals if you don't have your own equipment), and you get discounted food, drinks and things in the village. You can also get discount on hotel rooms.
1: Favoritism. I saw another person on here saying something called "The Gang", and I agree with that. If you are in this so called "Gang", you can get away with anything. I have come across some people not doing anything, and others getting heckled even when they work twice as hard as their co-workers. Some departments are better than others at this.
2: Scheduling. They ask you for your schedule preferences, then (usually if you aren't in "The Gang") they ignore them. I had to talk to several managers and supervisors just to get hours that I am comfortable working.
In conclusion, Blue Mountain is a great place to work, but you have to watch out for a couple things.
