Pros
If you enjoy working with high-functioning sociopaths that only have their best interests in mind and will throw you under the bus whenever there's a slight bump in the road, then TD is the place for you. There are some good managers, but they'll have a loyal teams with little turnover, so it's hard to work for the good ones. High turnover in I.T. departments = bad department managers and poor leadership.
Cons
TD will promote PMO/IT/Delivery managers from other business units based solely on their overall seniority, even if they lack the critical technical skills required to understand, or appreciate the complexities of the enterprise architecture of a huge company with 85,000 employees. As a result of their lack of knowledge, there is rampant mistrust in their Project Managers, BA's etc. and they'll instantly play the "Blame Game" whenever something goes wrong, even if it's very small or expected when dealing with I.T. projects. TD may have the will, but they don't always give you the means to achieve. Everything is the PM's fault - even if there's lack of resources and you're the acting BA, SA, and SME. If key stakeholders never show up to your meetings, it's your fault. If technical things naturally happen during execution, it's your fault since you're expected to foresee any and every possible outcome or scenario, which is impossible, and this will hurt your performance rating.
