A good interview question is:

Write a skills matrix for an engineering team.

That gives you an insight about what the candidate thinks seniority is, and how they are spending their efforts to move their career forward.

Is this an interview question for the candidate, or a question for the employer? Why should the candidate be writing a skills matrix for an engineering team if that's sounding an awful lot like a management task?

Or am I confusing your post for an eng manager interview and not an IC?

A question for the engineer.

You should at least know what the journey is, even if you haven't made it to the end.
