Pros

Well structured, relatively good benefits (dental sucks), 401K, EAP, etc. Good technology. Excellent focus on safety. Good customer service/customer success ethic/committment. Great reputation.

Cons

Be very careful accepting a position as a project manager. Promises of projects, remote work, etc. can be "fluid". In my case, the project styles promised, and the promise of "80% remote/20% travel to customers" was completely false.
