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
Technical proficiency
35% weight
Check fluency with GIS and geospatial stacks: QGIS or ArcGIS Pro, Python (rasterio, geopandas) or R, plus yield monitor cleaning, NDVI/NDRE indices and soil EC layers.
Evidence to listen for
Command of the languages, frameworks, and data tools the role actually uses
Understands correctness, performance, and failure modes, not just syntax
Has opinions on testing and can justify them
Reads and reasons about code they did not write
Five-point scoring guide
1
Poor
Cannot work independently; fundamentals are missing.
2
Needs Improvement
Weak fundamentals; output needs heavy review.
3
Satisfactory
Competent for the role; needs guidance on complex or unfamiliar work.
4
Very Good
Strong practitioner; handles hard problems with little guidance.
5
Excellent
Names specific libraries and workflows, describes cleaning raw combine yield data, and builds variable rate prescriptions that loaded correctly into machine displays.
02
Evaluation factor
Systems and trade-offs
25% weight
Probe how they handle imagery resolution versus cost, satellite (Sentinel, Planet) against drone flights, and integrating John Deere Operations Center, Climate FieldView or Trimble telematics feeds.
Evidence to listen for
Reasons about scale, latency, cost, and failure before writing code
Names the trade-off they chose and what they gave up
Understands the data lifecycle end to end
Anticipates what breaks at ten times the volume
Five-point scoring guide
1
Poor
No thinking beyond the immediate task; no awareness of scale or failure.
2
Needs Improvement
Limited architectural awareness; struggles with design decisions.
3
Satisfactory
Works within an existing design; makes sound local decisions.
4
Very Good
Designs for scale and maintainability; articulates trade-offs clearly.
5
Excellent
Weighs revisit frequency, cloud cover and pixel size against agronomic decisions, and explains why a cheaper data source sufficed for a given field trial.
03
Evaluation factor
Evidence and rigour
25% weight
Test statistical rigour on strip trials and on-farm experiments: replication, spatial autocorrelation, checking whether a yield lift is real or field variability.
Evidence to listen for
Validates results rather than trusting output
Knows how their work is measured and what a bad result looks like
Can describe a time their own analysis or model was wrong and how they caught it
Careful about data quality, leakage, and silent failure
Five-point scoring guide
1
Poor
Ships unvalidated work; no notion of how correctness is checked.
2
Needs Improvement
Validates superficially; misses obvious quality or leakage issues.
3
Satisfactory
Reasonable checks in place; rigour drops under time pressure.
4
Very Good
Validates thoroughly; can name a real error they caught in their own work.
5
Excellent
Insists on replicated randomised strips, quantifies uncertainty, and has told an agronomist or grower that a claimed treatment response did not hold up.
04
Evaluation factor
Collaboration and communication
15% weight
Assess how they translate maps and models for growers, agronomists and equipment dealers who will not read a confusion matrix or an R script.
Evidence to listen for
Explains technical work to non-technical stakeholders
Gives and takes code or peer review constructively
Documents enough that the work survives their absence
Aligns with team process rather than working around it
Five-point scoring guide
1
Poor
Cannot work in a team; resistant to feedback.
2
Needs Improvement
Communication issues create rework; lone-wolf tendencies.
3
Satisfactory
Adequate team member; documentation and review participation are light.
4
Very Good
Communicates well; reliable reviewer and collaborator.
5
Excellent
Shows field-day presentations or one-page prescription summaries, and describes changing an agronomist's seeding plan through evidence rather than dashboards alone.
