Why pre-screen research assistants before the lab interview
The failure mode in this role is quiet and expensive. An assistant who reruns an assay until it produces a plausible number, or who writes up what the protocol said rather than what they did, can invalidate months of work without anyone noticing until analysis. Applications cannot distinguish that person from a careful one, because both list the same techniques and the same degree. A short screen asks how they handle an unexpected result, which sorts them immediately.
What actually matters when screening Research Assistant candidates
- 01
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.
- 02
Results that went somewhere
Probe what their data fed into: a named publication, poster, conference abstract, grant renewal, or thesis chapter, and their stated contribution to each.
- 03
Troubleshooting and reproducibility
Test how they handle failed runs: contaminated cultures, drifting standard curves, missing participant data, or results that would not replicate across batches.
- 04
Documentation and collaboration
Look for lab notebook discipline, ELN use, IRB or IACUC submissions, chain of custody, and how they hand work to the next student or postdoc.
Pre-screening questions to ask Research Assistant candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Protocol and adaptation
3 questions01Can you describe a research project you have worked on?
Listen forTheir own tasks separated from the study as a whole, with what they ran independently and what they were supervised on.
Describes the study's aims with no account of what they personally did day to day.
02Do you have experience with qualitative and quantitative research methods?
Listen forAn honest statement of which side they have worked on, with the specific techniques or instruments they operated themselves.
Claims both with detail on neither, or methods listed from a syllabus rather than from practice.
03Do you have experience assisting with the design of research studies?
Listen forAny input into design, however small, such as suggesting a control or spotting a confound, showing they think beyond executing steps.
Purely task execution with no engagement in why the study was structured that way.
Work that was used
3 questions04Are you familiar with data collection and analysis?
Listen forData they collected and analysed themselves, with the software named and a decision they made about how to handle it.
Data handed to a supervisor for all analysis, or software named with no analysis they performed.
05Do you have experience conducting literature reviews?
Listen forA search strategy they can describe with databases named, plus how they decided what to include and exclude rather than reading widely.
Literature searching described as reading around the topic, with no systematic method behind it.
06Do you have experience preparing reports on research findings?
Listen forSomething they wrote that was used, whether a section of a paper, a report or a conference poster, with what feedback changed.
Writing limited to coursework, or contributions to papers they cannot describe.
Reporting anomalies
3 questions07How have you handled conflicting data or unexpected results?
Listen forReporting it to the supervisor, checking controls and documenting the anomaly, rather than repeating until the result looks acceptable.
Reruns until the number looks right, or discards outliers without recording that they did.
08What is your approach to problem-solving when faced with a research obstacle?
Listen forA structured attempt before escalating, with a specific problem they diagnosed themselves and what they tried in order.
Escalates immediately with no attempt, or persists alone for days without telling anyone.
09How do you handle feedback from supervisors or peers during a project?
Listen forA specific piece of critical feedback and what changed as a result, including feedback they initially disagreed with.
Feedback described only in positive terms, or an example where nothing actually changed.
Reproducible records
3 questions10Can you describe a time your attention to detail affected the outcome of a project?
Listen forA specific error caught, whether their own or someone else's, with what they were checking against when they found it.
Attention to detail claimed as a trait with no example, or an error caught by someone else.
11How do you handle data confidentiality and privacy?
Listen forPractical handling: anonymisation at collection, secure storage, and awareness of what their ethics approval permits them to keep.
Participant data kept on personal devices, or confidentiality described only as not discussing the study.
12How do you manage deadlines in a research project?
Listen forRealistic planning with time allowed for things failing, plus a case where they told a supervisor early that something would slip.
Deadlines met by rushing the final steps, or a slipped deadline that was not flagged in advance.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Technique and experimental design
35%5Names specific assays or study designs run independently, explains controls, sample sizes and why the design answered the PI's question.
Results that went somewhere
25%5Points to authored or acknowledged outputs, describes the dataset they generated and how findings changed the lab's next experiment.
Troubleshooting and reproducibility
25%5Walks through isolating one variable at a time, checking reagent lots and instrument calibration, and reruns before reporting anything.
Documentation and collaboration
15%5Keeps dated, auditable records others reproduced from; has drafted ethics amendments and trained incoming students on procedures.
An assistant who reruns until the number looks right invalidates months of work quietly. A one-way video screen surfaces that instinct before a lab interview.

Process basics
How long should a pre-screening round for a research assistant take?
Ten to fifteen minutes across eight to ten questions, answered async. Enough to confirm which techniques they have run independently, hear how they handle an unexpected result, and check their record keeping before a lab interview.
How much should undergraduate project work count?
It counts, as long as they can describe what they personally did and what went wrong. A final year project run largely by a supervisor is worth less than a summer placement where they were left to troubleshoot something themselves.
Evaluating answers
What is the strongest signal when screening a research assistant?
Willingness to report a result that looks wrong. Assistants who understand research describe telling the supervisor, checking controls and documenting the anomaly. The alternative, quietly repeating until the number looks right, is the single most damaging habit in this role.
How do I test record keeping quickly?
Ask whether someone else could repeat their work from their notes. Good answers describe recording deviations, lot numbers and settings as they go. Anyone who writes up at the end of the week is reconstructing rather than recording.
