Technique and experimental design
Check which protocols they ran unsupervised: PCR, ELISA, cell culture passaging, survey instrument design, or SPSS/R coding, and who wrote the protocol they followed.
Evidence to listen for
- Runs the assays and instruments themselves rather than describing what a team does
- Designs experiments with controls, replicates, and a stated hypothesis
- Knows what each technique can and cannot resolve
- Understands the science, not only the protocol
Five-point scoring guide
Protocol follower with no experimental design; cannot justify controls.
Runs standard assays; designs experiments poorly or not at all.
Competent at the bench with sound routine design.
Designs rigorous experiments and understands the limits of each technique.
Names specific assays or study designs run independently, explains controls, sample sizes and why the design answered the PI's question.
