Pros

Company is large and therefore many opportunities to change jobs within.

Cons

Change management is difficult in such a large company. Pay was not commensurate with similar roles in other industries.

Pros

Great benefits with 5 weeks paid vacation without having to accrue time. Also up to 3 months of paid parental leave. They have medical, dental, vision and group legal that you can opt in for. They also have a variety of wellness benefits such as personify health which pays you up to $225 a year for maintaining healthy habits and Lyra for mental health support.

Cons

It's a big company that moves pretty slowly. Not a lot of opportunity for development outside of my role for the group that I work for. Currently going through a lot of organizational changes.
