What the board assess
6 things the board is weighing
Command of fundamentals
Explains the core of their own discipline from first principles, not from a remembered formula.
Applied problem solving
Sets up an unfamiliar practical problem and reasons to an answer aloud, with an estimate where a number is needed.
Depth of own work
Knows their project or thesis — what they personally did, why, what failed, what they would change.
Clarity
Explains a technical idea so a panel member from another discipline could follow it.
Intellectual honesty
Says "I don't know" and reasons from what they do know, instead of bluffing.
Motivation and fit
Has a specific reason for this organisation and a realistic picture of the job and the posting.
