10 Essential Questions to Ask When Interviewing Medical Laboratory Technologists (2025)

1. Why Medical Laboratory Technologist Interviews Are Getting Harder to Run

In 2025, the applicant pool for MLT openings has ballooned, with many resumes and applications enhanced by AI tools. Even with AI-enabled resume screening, it’s tougher to spot applicants who genuinely understand lab diagnostics and quality control. As diagnostic workflows become more complex and regulated, interviews must be intentional and structured to uncover true technical depth. Recruiters now need sharper questions and clearer scoring to distinguish standout laboratory professionals.

2. Core Traits to Look for in MLT Candidates

A shared focus on essential traits makes vetting easier:

Technical Competence – The ability to accurately perform assays and operate lab instruments is foundational.
Critical Thinking – Lab technologists must evaluate results, notice discrepancies, and apply logic to troubleshoot errors.
Attention to Detail – Inaccuracy in sample handling or record‐keeping can compromise patient safety—precision matters.
Quality Mindset – Strict adherence to protocols and quality assurance ensures regulatory compliance and reliable outcomes.
Collaboration – Working effectively with pathologists, clinicians, and lab team members supports seamless workflow and diagnostics.

3. Personal and Career Background

A clear candidate profile helps streamline sourcing:

Degrees in Medical Laboratory Science, Clinical Laboratory Technology, Microbiology, or Biomedical Science are common.
Experience in hospital labs, reference laboratories, blood banks, or research settings is typical.
Many progress from roles like Medical Lab Assistant, Histotechnician, or Junior Technologist before moving into full MLT positions.
Familiarity with accreditation standards (e.g., CAP, CLIA) or certification bodies underscores technical readiness.

4. Technical Skills and Experience

Technical excellence is critical for MLT success:

Mastery of manual and automated assays (e.g., hematology, microbiology, chemistry) enables accurate test results.
Proficiency in operating and troubleshooting lab instruments such as analyzers, centrifuges, and PCR machines.
Experience with laboratory information systems (LIMS) ensures smooth sample tracking and data handling.
Knowledge of quality control processes: calibration, validation, and documentation practices.
Understanding biosafety protocols and risk management to protect both staff and patients.
Familiarity with point-of-care testing devices and validation procedures broadens diagnostic capabilities.

5. Soft Skills

Soft skills often make or break fit in a structured lab environment:

Communication – Technologists must clearly document results and collaborate with team members and clinicians.
Adaptability – Shifts in test volume, new assays, or emergency situations require flexibility and quick thinking.
Ownership – Taking responsibility for errors and following through on corrective action demonstrates accountability.
Teamwork – Interdependence with colleagues in processing, checks, and cross‐coverage is essential.
Calm Under Pressure – In high-volume or urgent cases, steady performance safeguards quality and safety.

6. The Best Interview Questions to Ask and Why

When interviewing Medical Laboratory Technologists, ask questions that uncover technical grounding, problem-solving approach, and communication clarity:

“Describe a time you identified an instrument error—what happened and how did you resolve it?”
Tests troubleshooting ability and technical ownership.
“How do you handle a QC result outside limits—what steps would you take?”
Reveals understanding of quality control processes and adherence to protocols.
“Tell me about a time you disagreed with a colleague on a result—how did you address it?”
Shows professionalism and communication in collaborative contexts.
“Explain how you prioritize high-acuity samples during your shift.”
Assesses time management and decision-making under pressure.
“What methods have you used to validate a new assay or instrument?”
Demonstrates technical rigor and compliance with validation standards.
“Describe a process you improved in your lab—what was your role and impact?”
Highlights initiative and focus on efficiency or quality.
“How do you stay current with new diagnostic technologies or regulations?”
Indicates continuous learning and adaptability.

7. Good vs. Bad Interview Questions

Good interview questions are open-ended and scenario-based, allowing candidates to walk through real examples and showcase their thought process. For instance, asking, “Describe a time you resolved a QC failure—what steps did you take?” encourages candidates to explain lab protocols, corrective action, and communication with supervisors.

In contrast, bad questions are leading or closed, offering little insight—for example, “You follow QC protocols, right?” can be answered with a simple “yes” and doesn’t reveal how they think or act.

8. Scoring Candidates Properly

A structured rubric promotes consistency and objectivity by highlighting the most critical competencies for the role.

9. Red/Green Flags to Watch Out For

Recognizing red and green flags quickly helps prioritize top candidates.

Red Flags:

Blaming equipment without investigating root cause – suggests lack of troubleshooting mindset.
Vague answers on QC failures – implies weak process understanding.
Poor team communication examples – may lead to workflow issues.

Green Flags:

Describes specific corrections after QC failures – shows ownership and knowledge.
Speaks to protocol changes implemented – implies initiative for improvement.
Shares certifications or recent training – indicates continuous learning.

10. Common Interviewer Mistakes

Interviewers often over-rely on technical checks and underplay soft skills or process thinking. Unstructured interviews can lead to inconsistent candidate evaluation. Leading questions can influence answers and hurt fairness. Neglecting scorecard calibration across interviewers may result in misaligned hiring decisions and potential bias.

11. Tips for the Medical Laboratory Technologist Interview Process

Interviewing MLTs is smoother with structure and clarity:

Define a Success Profile – Establish required technical skills, lab environment experience, and quality attitudes upfront.
Use Structured Scorecards – Standardize assessment across competencies like QC, communication, and adaptability.
Calibrate Interviewers – Discuss case examples together to align evaluation standards.
Limit Rounds to Key Stakeholders – Prioritize technical lead, QA manager, and operations decision-makers.
Allow Time for Candidate Questions – Let candidates ask about lab systems, accreditation, or shift schedules.
Provide Prompt Feedback – Update candidates quickly to maintain engagement in a tight labor market.

12. How to Run Remote & Async Interviews That Actually Work

For remote or async interviews with MLT candidates, structure and clarity remain key:

Use tools like Zoom or Microsoft Teams for video walkthroughs of sample instruments or workflows.
Provide realistic asynchronous tasks—e.g., reviewing anonymized QC data and writing up next steps.
Set clear instructions and deadlines so candidates know exactly what’s expected.
Apply the same rubric for async exercises as in live interviews to ensure parity.
Communicate timelines clearly and follow up promptly to keep candidates engaged.

13. Quick Interview Checklist

A simple checklist keeps the process smooth and aligned:

Start with an intro: mention candidates should come ready to discuss instruments, QC, and lab workflow.
Share scorecards and expectations with interviewers.
Screen resumes using defined criteria (degrees, certifications, experience).
Schedule initial call to confirm communication skills and work style.
Assign an asynchronous QC review exercise where candidates identify and correct sample issues.
Hold a technical deep-dive on instruments, assays, and troubleshooting examples.
Conduct a behavioral interview covering collaboration, ownership, and adaptability.
Review scorecards and compare ratings with calibrated panel feedback.
Flag strong candidates for reference checks focused on technical proficiency and teamwork.
Make a data-driven decision and schedule final offer presentation.
Provide prompt feedback to both selected and non-selected candidates.
Onboard selected candidate with training plan and accreditor readiness.
