Assessment flow
Use the same role-relevant question set and scoring framework across candidates to improve fairness, comparability, and hiring confidence.
Select junior, mid-level, senior, applied-NLP, or LLM-focused questions based on the role and expected ownership.
Ask candidates to design pipelines, compare models, debug tokenisation, explain attention, evaluate outputs, and solve retrieval problems.
Evaluate language understanding, modelling depth, coding quality, metric selection, error analysis, deployment thinking, and communication.
Use structured scorecards, skill breakdowns, and question analysis to identify candidates for the next hiring stage.
