Pros
Stable company committed to it's community, and doing the right thing. There are many challenging opportunities throughout the organization and business units, which gives people opportunities to try new things, and challenge themselves. The company wants people to work hard, but understands that employees also have lives, and that work life balance is important to many people. Always looking for ways to expand the business through sensible, lower risk investments to stay viable. Also great people and culture!
Cons
Being a large, utility style business, change tends to happen slowly with layers of bureaucracy. Many people have also built long careers at Sempra, and tends to push against change that they perceive as threatening. To be successful you have to be patient, and sometimes accept the politics. But that is something that every large company will have, and sometimes is necessary to prevent making bad decisions.
