The company and culture will suck you dry. Your soulless exoskeleton will have a tough time finding another job while being pummeled to death by relentless demands. It's not coming from just one person, as a matrix organization it's more like death by a thousand cuts. The longer you work there, the more people in far off departments will remember you, and line up at your desk/email you and copy bosses demanding urgent actions. As a global company, this is 24/7 and sometimes in a language you can't read. In the beginning it's fun and very interesting. A great challenge. But everyone has a limit, and you will get there eventually.
In the early days everything is cool. You can start something new, build it up, make it awesome. Then support it forever, have more similar things dumped on you, and watch all the new flashy interns working on the cool stuff. Once you take something on, you can almost never escape it. If you get an intern, management expects you to give them the cool stuff and keep the garbage for yourself. It makes sense to continue the cycle of entrapment.
Internal mobility is a joke, a way for management to pass off under-performing staff or people they don't get along with. If you do a good job, you are stuck, and your manager can stop you from moving anywhere else. You might need to quit and re-join to move within Tesla. So make sure you like the job if you accept it, forget getting your foot in the door and then shifting to something you like better.
