Theoretical command
Probe depth on transformer internals, scaling laws, RLHF and RL objectives, mechanistic interpretability; ask them to defend a position on emergence or sample efficiency with citations.
Evidence to listen for
- Explains the underlying theory at the level the role demands, and can go a layer deeper when pushed
- Knows which results are established and which are contested
- Distinguishes their own contribution from the field's
- Comfortable saying where the theory runs out
Five-point scoring guide
Recites terminology without understanding; cannot go one layer deeper.
Surface familiarity; conflates established results with speculation.
Solid grasp of the core theory; thin at the frontier.
Strong command; separates settled results from open questions.
Argues precisely about optimisation dynamics, loss curves and inductive bias, citing specific papers and naming where the theory breaks down.
