Pros
You will get to see many parts of the company. You will put hands on many aspects of a world-class orbital rocket. You will travel if you are competent and adapt quickly to off-nominal situations. The work is fulfilling knowing you're a contributing part of the highest cadence rocket company in the world.
Cons
There exists a very strong work/work balance. Check your personal life at the door. This will only increase as the cadence increases. You sink or swim and learning is done by firehose. You will develop inefficient methods of using their systems in your first few weeks and months. This is compensated for by working harder and longer. Open positions and promotions are mostly predetermined and it can be difficult to transfer if your immediate management does not like you.
