FWIW, that's how I structure my interviews typically, so they still exist in some places.

For anyone reading along I highly encourage that; there's way more signal to noise hearing about some project they worked on and why they were proud enough to put it on their resume than 'did they remember the algorithmic call/response'. You can't beat an almost post mortem discussion where you let the interviewee lead on what they think went well and what they'd have done differently with hindsight.
