Pros
When the job is good at Summit, it's great. You're surrounded by great people in an environment focused on passion for climbing, fitness, and the outdoors. Any down time can always be filled with socializing with the interesting visitors or independent tasks of your choice, which is nice. The perks also rock, including free membership and huge gear discounts.
Cons
As much as the job can be an amazing experience and time, it can also inevitably be the opposite. Decisions by management are often poorly(or not at all) thought out, including who gets promoted and manages gyms. Overall, the day-to-day experience is fully dependent on whom is managing and whether there is anything to do. As well, moving up is somewhat pure luck and not something you can expect.
