Pros
Ability to learn a great deal, both about their systems, and the tools and processes they use to serve the customers. A wide variety of benefits, for full-time permanent employees.
Cons
Grueling work, at least in the high-visibility team I was in, Not great for sensitive people, who like and may need solid training. (not ad-hoc, fragmented training that's sprung on you sometimes) The expectation that "as a BizOps Engineer," you are expected to handle things yourself much or most of the time. This included the expectation you were to handle 100% of the communication, research, fixing, and ITSM tickets during an Incident. From my research, including use of AI, the work made the ADHD tendencies for someone who has it, worse, not better. This affected me and my family. Your mileage may vary, of course.
