Staying on top of documentation helps me track project progress and plan my workload efficiently.
Describe Your Experience with Quality Control.
Quality control is a central duty, so demonstrate your experience and attention to detail.
Sample Answer: Quality control is essential to ensure consistent, reliable results. In my previous roles, I performed QC including visual inspections, sterility testing, and cell viability assessments. I was responsible for calibrating equipment, testing reagents for contamination, and verifying supplier certifications. Attention to detail is critical, so I always double check my work. I understand the huge impact QC has on research integrity.
How Do You Work with Others on a Team?
Focus on your collaboration, communication, and conflict resolution skills. Use examples if possible.
Sample Answer: I work very collaboratively and always maintain open communication with lab colleagues. I provide assistance when needed and am comfortable both taking direction and taking initiative. If any conflicts arise, I focus on logical problem-solving based on what’s best for the overall project. My goal is fostering positive, productive team dynamics.
How Do You Ensure Accuracy When Recording Data?
Scientific integrity depends on accurate data, so this question is key. Discuss your methods.

How Do You Learn from Mistakes? Share an Example.
Your response demonstrates maturity, self-awareness, and commitment to growth
Step 3: Ask the interviewer questions
Remember that an interview is a two-way street. Just like an employer will check to see if you have the right experience for the job, you need to check to see if this is the right chance for you.
Q3: “Review your CV and experience.”
If the hiring manager asks you what you can bring to the table, you should be able to talk about it from a scientific point of view. For example, you shouldn’t just say that you’re a hard worker and a dedicated team player; you should be able to say that you’ve used certain techniques or are interested in certain fields of science.
If you don’t have experience in a particular scientific field, don’t worry. Instead, you could say that you want to gain more experience in this area, improve your skills, and move up in your career.
That said, previous hands-on experience will help you stand out. One effective way to make this point clear is to list the three most important lab techniques you are familiar with.
These techniques will vary depending on your field of science. For molecular biology, you may already know how to use PCR (polymerase chain reaction), gel electrophoresis, ELISA (enzyme-linked immunosorbent assay), and cell culture.
High-performance liquid chromatography (HPLC), gas chromatography (GC), and/or mass spectrometry (MS) are likely to be things you know how to use if it’s analytical chemistry.
TIP: No matter what you’re interested in or how much lab experience you have, you need to be able to describe how you’ve used certain techniques or health and safety rules. That’s great that you say you have experience, but you need to be able to back it up with examples.
