Pros
TI is pretty great, especially if you're in an engineer. There's a great emphasis innovation from the leadership, great opportunities to work on cutting edge technologies. Diversity network is amazing! If you do join TI, definitely get involved. Great opportunity to network across departments and learn something new. TI truly believes that you shouldn't have to check out a part of you at the door. Our different backgrounds is what fuels innovation. IT isn't that great though. As a software engineer, it's hard not getting dulled by the "just get it to work" mindset. Unfortunately, this has created a lot of problems with our applications which are a nightmare to maintain and support. If you want to maintain your competitive edge as a software developer, then don't work in IT (unless you end up in one of the businesses as an software engineer). If you want to coast and retire, then this is the place for you.
Cons
A lot of management ropes to jump through to get things done, if you don't ask for opportunities, you won't get them. Management doesn't care about you and your growth. A lot of applications are legacy (we still use COBOL).
