Have you ever performed testing for middleware?
Firmware engineers perform duties in addition to designing firmware and writing code. One of these duties is testing their software as well as other components of the system it interacts with. One of those components is called middleware. This question will test your knowledge of middleware and inform the interviewer of your experience interacting with this component and testing it to ensure that the code you write is compatible with it. Most firmware engineers have experience in this area.
"I have a great deal of experience working with middleware. Since much of the code I write needs to interact with this layer, I get involved in the testing to assure that the two pieces of code are interacting appropriately. Some of the components I verify include the middleware's ability to provide authentication and messaging across the system."
