Pros
DNC operates in some of the biggest venues in the world from sporting venues, to national parks, to convention centers. This can make the day to day work very exciting and fast paced. Because there are numerous other venues, there are many resources for management to turn to. There are constantly internal job postings, which could allow for job growth within the company if you are willing to relocate.
Cons
Challenges may very depending on the venue in which you work. At a corporate level, the company tends to be very adverse to change. Non-management office staff and admin have very little opportunity for training at a corporate level, which can become difficult since they do upkeep daily operations. Also, employment at sporting venues may be sparse during the off-season, making relying on DNC for a primary job difficult for seasonal and non-management office staff.
