I love the type of work, I was always moving and lifting heavy components.
I learned about chillers, sensors, transformers, ratings, and how to read schematics. Also how to manage a team of workers.
Management (supervisor and higher) needs major improvement.
I got along with all coworkers, they were very experienced and helped me learn.
The hardest part of the job was modifying without proper dimensions.
The most enjoyable part was connecting conductors.
