Spiking Neural Networks (SNN) Developer interview scorecard

Evaluate Spiking Neural Networks (SNN) Developer candidates across 4 weighted areas: theoretical command, from theory to hardware or code, research judgement, and explaining it to non-specialists. Theoretical command leads at 35%, so probe command of LIF, Izhikevich and adaptive neuron dynamics, STDP versus surrogate gradient training, rate versus temporal coding, and why. Use the rubric to compare role-specific evidence consistently.

TL;DR
For theoretical command, look for evidence the candidate derives surrogate gradient behaviour and membrane dynamics from first principles, and states clearly where spike-based coding beats dense activations. For from theory to hardware or code, look for evidence the candidate names deployed models with measured energy per inference, spikes per sample and latency on real neuromorphic hardware, not simulator-only results. Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

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

Probe command of LIF, Izhikevich and adaptive neuron dynamics, STDP versus surrogate gradient training, rate versus temporal coding, and why ANN-to-SNN conversion loses accuracy at low timestep counts.

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

Derives surrogate gradient behaviour and membrane dynamics from first principles, and states clearly where spike-based coding beats dense activations.

02
Evaluation factor

From theory to hardware or code

30% weight

Ask what they built in snnTorch, Norse, Brian2, NEST or Lava, and whether it ran on Loihi 2, SpiNNaker or Akida silicon rather than GPU simulation.

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

Names deployed models with measured energy per inference, spikes per sample and latency on real neuromorphic hardware, not simulator-only results.

03
Evaluation factor

Research judgement

20% weight

Test how they chose timestep counts, neuron sparsity targets and datasets (DVS Gesture, N-MNIST, SHD), and when they abandoned a spiking approach for a conventional net.

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

Sets accuracy and energy budgets upfront, kills unpromising encodings early, and honestly states where SNNs offered no advantage.

04
Evaluation factor

Explaining it to non-specialists

15% weight

Judge how they explain event-driven computation and sparsity savings to hardware leads, product managers or grant reviewers who do not know membrane potentials.

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 spike sparsity into power, latency and cost figures a non-specialist can act on, without diluting the technical claim.
