Pros
Since the company is big, it's a great opportunity for networking, learning new skills, and earning certificates after completing hazard safety training that you can use in the future as well (especially if you're working with Unity Lab Services). Coworkers are usually nice and will always lend a hand if you need it. If you're lucky, you might be placed at a one-person site where the site supervisor is chill and understanding, lets you work at your own pace, and helps you learn new things by giving you "side quests."
Cons
No real career growth. The workload can be hard to keep up with at times, and the company strictly enforces an 8-hour workday with no overtime, even when needed. Day-to-day operations feel heavily micromanaged by upper management through strict policies. HR introduces new policies almost monthly, often adding tasks that feel unnecessary. They frame this as becoming "more data-driven," but in practice, it hasn't led to much noticeable improvement.
