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.
A molecular technologist uses various laboratory techniques to analyze DNA, RNA, and proteins in samples.
Molecular technologists may work with samples such as blood, urine, saliva, tissue, and cells.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
As a molecular technologist, you will be responsible for conducting scientific studies and analyzing DNA for research purposes. This is a highly technical role that requires a solid understanding of molecular biology and lab techniques. Here are some tips to help you prepare for your molecular technologist interview:
Remember to be confident, enthusiastic, and show your passion for molecular biology during your interview. Good luck!
Raising the salary question too early in the interview process may give the impression that you're primarily motivated by money. Wait until a job offer is on the table before discussing salary.
