I work with tradeoffs every day, most of which are data derived, not problem derived & that is only visible from experiments on the data (sometimes across millions of ops).

I don't think I'd know how to interview someone for your position.

I do my best thinking when I'm running

I've had similar experiences. Of course I'm not possessed by the idea that interviews are very good as a general mechanism. I've given allowances for nervousness and pressure. I certainly know what it's like to be on the other side of the table. Even allowing for all of those things, it leaves me wondering.
