Pros
Southern has been good to me during my career. There are great people that have poured into me and helped me grow in my career. The size of the company allows you to try a variety of things while trying to find out exactly what you may want to specialize in. It provides very good benefits and I have been able to have a ton of flexibility with my day to day.
Cons
It is a utility. It is regulated which means it limits the amount of profit that the company can make. This almost puts a cap on your earnings. However, provides a decent level of security depending on the part of the company you work for. As with any large company, your direct leadership matters A LOT. It is a 24/7 business so there are periods where work life balance are nonexistent but good leadership have always made up for it
