Pros
The company really looks after their employees. There is plenty of space for personal development and training to build you up as an employee. Everyone is interested in your development, not just your manager which means that you are given so many opportunities to grow in many ways.
The employee resource groups are also fantastic, they are very active and work hard to put on events to keep you engaged. PRIDE@MBDA have been especially good at making me feel welcome, from rainbow lanyards to Q&As about being non-binary, they do a fantastic job of not only making it clear queer folk are welcome, but also educating those outside the community on how to be more inclusive.
Cons
It is hard to find parking in the middle of the week when everybody is in the office.
