Avantages
TI can provide a diverse set of career options to an engineer. It is upto you to find what you will like and pursue it. This diversity is very good. Furthermore, although people complain about schedules and how much work they are piled up with, my observation is that people have a pretty healthy work life balance here.
Inconvénients
If you are a person with a technical career track in mind and yet you also want to be moving up in the management path, it is very difficult to do that in TI. TI is managed by sales oriented people. They might be running a company which could be selling anything. They happened to find themselves in the semiconductor field. So, either switch to marketing related roles (which are plenty by the way) and try your chances there or if you want to stay as a technical person, then accept the facts at the beginning and try to be content with your life with some other things.
