Pros
There are a ton of wonderful people and Jabil definitely knows how to throw a party. Jabil prides itself on promoting from within, and definitely does, even if not for the right reasons.
Cons
I reported my manager through the integrity hotline for filling a position with someone who obviously had a conflict of interest (the person was on the interview panel for that position). The report went straight to the internal HR manager. HR exists to protect the company and Jabil is no different. To their credit HR did find wrong doing, but the person with the conflict of interest got to keep their new position. I don't know if the hiring manager faced any repercussions but HR assured me it was "handled". I should mention that everyone involved has been with the company for multiple years and have taken Jabil's yearly ethics training that covers exactly this type of scenario. Shortly after all of this I got the worst yearly review of my 6 year tenure that had flat out lies about me. The explanation I got was that "people above me" gave the feedback but not a single example was given. I was then laid off at the beginning of the year. I was the only person in the entire department that was let go as part of a RIF. I was a level 2 engineer, and even though the workload is exactly the same for all engineers they are still desperately hiring for level 1 and level 3 engineers.
