What a strong answer includes: List them.
2. “Describe a contamination investigation.”
What a strong answer includes: Explain.
3. “How do you prevent contamination?”
What a strong answer includes: Aseptic technique.
4. “What biosafety levels have you worked in?”
What a strong answer includes: Share.
5. “Why microbiology?”
What a strong answer includes: Share interest.
Practical skills checks
A short demonstration beats a perfect resume. Ask candidates to talk you through, or perform under supervision, tasks such as:
- Perform a Gram Stain (see the steps)
- Monitor a Clean Room (see the steps)
- Investigate Contamination (see the steps)
Red flags
- Can’t describe basic safety practices for the role
- Vague or inconsistent work history with no explanation
- Unfamiliar with core terms such as Pathogen, Culture, Gram stain
- Negative talk about every past employer or coworker
Onboard for retention
The first 90 days decide whether a new hire stays. Use our Microbiologist 30-60-90 day onboarding plan and give every new hire the same foundation with Microbiologist training. Show them the path forward: Microbiology Technician → Microbiologist → Senior Microbiologist → QC or Lab Manager.
