Possibilities are endless if you have the right degree. - Avis employé Process Chemist Shell

If you're not an engineer you'll be overlooked. Performance reviews are extremely biased towards those that are in the right role at the right time. I saved the site over $3,000,000 last year and that wasn't enough for anything more than an average performance review. Had I been and engineer, I would probably have been promoted and given a huge bonus. GE invented the performance review process Shell uses and recently GE gave up on it because it doesn't work. What does that say? It's not a bad place to work, you just have to want to play the corporate game.
