“Why?” is the whole interview.

Coding tests prove the what. Technical interviews probe the why — design choices, trade-offs, debugging instinct — with follow-ups that adapt to each answer while the rubric stays fixed.

Question 2 of 6 · references the candidate's own submission

Interviewer: In your assessment solution you chose a sorted-migration approach in rebalance(). What breaks first as node count grows?

Follow-up: “What if migrations can fail midway?”
Builds on real work

Questions can reference the candidate's own assessment submission — no abstract puzzles.

Fixed rubric, drafted follow-ups

Follow-up questions are written into the template when it's built; the scoring anchors never move.

Engineer-reviewed

Transcripts and scores go to a technical reviewer before ranking — disagreement is logged, not hidden.

A complete signal

Test the code.
Interview the engineer.

Pipelines that pair a coding assessment with a technical interview see both halves of competence — execution and judgement — for under two hours of candidate time.
