I've experienced this and I think it's due to skills matrix bingo. You're a junior engineer and to become a senior engineer all you need to do is make a line in the skills matrix. Write a test! Be nice to someone in a code review! Boom! BINGO! Senior engineer. Of course it's good to know what you need to do to become a Senior. It used to be more wooly but at the same time even the best thought-out skills matrices don't capture what a Senior engineer really is.
