People in higher up positions like yourself will rarely be subjected to testing with tools like this. You are basically trying to remove the human from equation and industrialize the whole process.
If the interview was along the lines of upgrading the packages on the system, debugging why nginx was crashing, figuring out the specs of the system, etc. that is totally fine with me and I believe respectful of a candidates time. Unfortunately it always turns into something else when people need to come up with new "challenges" for canidates.
I wouldn't feel the need to do this if so many candidates didn't fail rudimentary tests. A SWE candidate MUST be able to write the function min(), in the language and tooling of their choice. But in an interview, a sizable fraction cannot. (The actual bar is far higher than min(), ofc., but min() ought to be trivial.)
