The objective of the Adapter design pattern is to enable "objects" to work together. Your statement of using the pattern to make two "systems" work together is a bit off key.
"Systems" and "objects" are not the same terms and cannot be used interchangeably, in my opinion.
I would have been looking for you to explain the what, why and how of what you implemented in the "project", rather than a rudimentary answer not related to the "project." Demonstrating that you might know the definition of a design pattern does not show that you have experience implementing the pattern.
