Top 20 Molecular Technologist Interview Questions and Answers

If you're looking for a career as a molecular technologist, congratulations! You're entering a growing and exciting field in laboratory medicine. To help you prepare for your job interview, we've gathered some of the most common and important interview questions and answers.

1. What is a molecular technologist?

A molecular technologist uses various laboratory techniques to analyze DNA, RNA, and proteins in samples.

2. What kinds of samples do molecular technologists typically work with?

Molecular technologists may work with samples such as blood, urine, saliva, tissue, and cells.

3. Can you describe your experience with PCR?

PCR, or polymerase chain reaction, is a common technique used in molecular biology to amplify DNA segments. Be prepared to discuss your experience with PCR, including specific protocols you have used and any troubleshooting you have done.

4. How do you ensure the accuracy of your test results?

Molecular technologists must be diligent and precise when testing results. You might talk about using strict quality control measures, or double-checking your assays and results to reduce the chance of error.

5. How do you stay up to date with the latest techniques and technologies in molecular biology?

Molecular biology is an ever-evolving field, and it's important to stay up-to-date with the latest technologies and techniques. This could include reading scientific journals and attending conferences and presentations.

6. How do you prioritize when performing experiments?

You may be asked how you prioritize your work, particularly if you're working on multiple projects simultaneously. You might discuss your ability to set goals and deadlines, how you organize your work, and how you ensure you don't lose track of your priorities.

7. What techniques and assays are you most familiar with?

Molecular technologists should be familiar with a range of molecular techniques and assays, including PCR, gel electrophoresis, and DNA sequencing. You should be able to discuss the principles behind each of these techniques, as well as any specific protocols you've used.

8. How do you handle difficult problems that arise in the lab?

It's not uncommon for problems to arise during experiments or tests. You might talk about how you troubleshoot these problems, including how you ensure they don't recur in the future.

9. Can you describe your experience with bioinformatics?

Bioinformatics is the use of computer algorithms to analyze large biological datasets. Molecular technologists may be asked how familiar they are with bioinformatics, including what software tools they've used.

10. Can you describe your RNA extraction experience?

RNA extraction is a common task in molecular biology, particularly for gene expression analysis. You may be asked to discuss your experience with RNA extraction techniques, including those that work with small amounts of starting material.

11. Can you tell us about a particularly challenging project you've worked on?

You may be asked about a project you worked on that was particularly challenging, such as troubleshooting a difficult PCR reaction or developing a new assay from scratch. Be prepared to walk through your thought process and how you overcame any obstacles.

12. Can you discuss your experience with sample preparation techniques?

Molecular technologists often work with biological samples that require careful preparation before they can be analyzed. You might discuss your experience with techniques such as tissue homogenization, cell lysis, or nucleic acid extraction.

13. What motivates you to work in molecular biology?

Take some time to consider what motivates you to work in molecular biology. You might discuss your interest in exploring the role of genetics in disease, your passion for problem-solving in the lab, or your desire to advance the field of laboratory medicine.

14. Can you discuss a time when you had to troubleshoot an assay?

Troubleshooting is a critical skill for molecular technologists. You may be asked about a time when you had to troubleshoot an assay, such as a PCR reaction that wasn't working as expected. Be prepared to discuss your thought process and any solutions you tried.

15. What experience do you have with real-time PCR?

Real-time PCR, also known as qPCR, is a common technique used to quantify nucleic acid samples. You may be asked about your experience with this technique, including how you troubleshoot any issues and what software you've used to analyze data.

16. How do you ensure the accuracy and reproducibility of your assays?

Accuracy and reproducibility are two important aspects of laboratory work. You might discuss your use of internal quality control measures, how you document your experiments, or what steps you take to ensure consistency across a series of experiments or tests.

17. Can you discuss a time when you had to work with a difficult sample?

Working with difficult samples is par for the course in molecular biology. You may be asked about a challenging sample you've had to work with, such as one with low RNA yield or degraded DNA. Be prepared to discuss your strategies for overcoming these kinds of obstacles.

18. How do you handle large datasets?

In molecular biology, it's common to work with large datasets that require careful analysis. You might discuss your experience with software tools like Excel, R, or Python, the kinds of algorithms you've used to analyze data, and how you ensure accuracy in your analyses.

19. Can you tell us about a successful project you've worked on?

Employers may want to hear about a successful project you've worked on in the past, such as developing a novel assay or contributing to a published paper. Be prepared to walk through your role in the project, what made it successful, and what you learned from the experience.

20. How do you maintain attention to detail during repetitive tasks?

Attention to detail is critical in molecular biology, particularly when performing repetitive tasks like pipetting or running the same assay multiple times. You might discuss your strategies for staying focused and avoiding distraction over long periods of time.

By being well-prepared with thoughtful and informed answers to these interview questions, you'll be able to demonstrate your expertise and experience as a molecular technologist, making you an excellent candidate for your desired position.
