This process still doesn't cover my problems.

I do have the experience, and have the code to show. Why would I be subject to a "homework"?

This process objectively discriminate against people with enough age and experience, but don't have the time outside work. Even just not having the will to do a "homework" is an enough reason to pass.

Are you hunting for young eager engineers who can put the most to self proving, or a diverse experience base?

I am not suggesting anything against your process, but highlighting the shortcomings.

I would probably pass your interview process directly.
