Pros
Lots of hands on experience with a wide variety of equipment and client groups make for experience that almost looks fake on a resume.
Cons
Endless scope creep on your list of responsibilities. Not enough staff. No one has enough time to develop any written standards for anything so there is nothing to train new staff on. All training is word of mouth and on the job. If you do make time to make up some documentation for a process or procedure Management will pull you into another dumpster fire that needs saving and accuse you of slacking off. Most Management doesn't understand how the business works or what the core issues are that are causing the problems. Very stressful work environment. You rarely have more than an hour to work on a 'top priority issue' before getting pulled off it to work on another 'higher priority issue' When they are strapped for employees they put out job postings offering postings for more money than people in those positions currently are making.
