What to assess and how to score it
Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
01
Evaluation factor
Theoretical command
35% weight
Check command of cross-modal representation learning: CLIP-style contrastive objectives, InfoNCE temperature effects, early versus late fusion, cross-attention adapters, and why modality collapse or shortcut learning happens.
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
1
Poor
Recites terminology without understanding; cannot go one layer deeper.
2
Needs Improvement
Surface familiarity; conflates established results with speculation.
3
Satisfactory
Solid grasp of the core theory; thin at the frontier.
4
Very Good
Strong command; separates settled results from open questions.
5
Excellent
Explains contrastive versus generative multimodal objectives precisely, names failure modes like modality gap, and cites specific papers behind their design choices.
02
Evaluation factor
From theory to hardware or code
30% weight
Probe what they built and trained: audio-text or image-text encoders in PyTorch, LoRA fine-tunes of LLaVA or Qwen-VL, sharded data loaders, FSDP or DeepSpeed runs, GPU hours consumed.
Evidence to listen for
Has built, simulated, or run something real, not only published about it
Knows the gap between the idealised model and the actual apparatus or system
Names the practical constraint that dominates in real conditions
Can describe a result that did not match prediction
Five-point scoring guide
1
Poor
Purely theoretical; no contact with implementation.
2
Needs Improvement
Some exposure but unaware of practical constraints.
3
Satisfactory
Has implemented work; understands the main real-world limits.
4
Very Good
Strong practical record; articulate about theory-versus-reality gaps.
5
Excellent
Walks through a multimodal model they trained end to end, quoting dataset scale, hardware, throughput, and downstream retrieval or VQA gains.
03
Evaluation factor
Research judgement
20% weight
Assess how they choose between scaling data, swapping the vision backbone, or fixing alignment; look for ablations, benchmark selection (MMMU, VQAv2, MSR-VTT), and abandoned directions.
Evidence to listen for
Chooses problems by tractability and value, not novelty alone
Knows when to abandon a line of work
Reads and evaluates others' results critically
Can say what would falsify their own approach
Five-point scoring guide
1
Poor
Chases novelty; no sense of tractability or when to stop.
2
Needs Improvement
Weak problem selection; persists past the point of value.
3
Satisfactory
Reasonable judgement within a defined programme.
4
Very Good
Selects problems well and knows when to abandon a line.
5
Excellent
Describes ablations that changed their mind, questions benchmark validity, and can name an approach they killed early with the evidence why.
04
Evaluation factor
Explaining it to non-specialists
15% weight
Test how they brief product, annotation vendors, or clinical or education partners on what a multimodal model can and cannot infer, including hallucination and caption bias risks.
Evidence to listen for
Explains the work to an engineer, an executive, or a funder without either mystifying or dumbing it down
Writes clearly
Collaborates across disciplines
Makes the case for resources in terms the audience cares about
Five-point scoring guide
1
Poor
Cannot communicate outside their specialism.
2
Needs Improvement
Explanation is either impenetrable or hollow.
3
Satisfactory
Adequate with technical peers; less effective with lay audiences.
4
Very Good
Explains clearly to specialists and non-specialists alike.
5
Excellent
Translates alignment and grounding limits into plain consequences for users, and has produced eval dashboards or memos non-researchers actually used.
