Vantaggi
Salary, I was compensated very well, the I hated working there so much that I resigned without anything even lined up. It was a good move for my mental health.
Svantaggi
The leadership in general are not very intelligent, disorganized, and uncommunicative. They were decades behind in certain areas that lead to massive inefficiencies and overwork. (Out of respect I will not be specific).
I suggested an improvement that would have taken task time down from 8 hours to virtually real time, but the executive Team, in their arrogance, did not allow me to implement the system. Sometime later, the cumbersome, unreliable system was not working and a deadline approaching. I worked 20 hours per day for 7 days and built an entire real time reporting system - then resigned. No one at AMAT was ever helpful. It always seemed an inconvenience to give a colleague outside ones group the time of day.
I gained absolutely ZERO new skills or professional development at AMAT all my time there.
Many of the employees at the time, including senior management, felt free to publicly express invectives against the current POTUS in their suffering TDS. Another reason I could not work in the environment. Rules for thee and not for me.
