Why Did You Choose to Pursue a Career in Molecular Biology?
This opening question allows you to share your motivations and passion for this field. Focus your answer on your interest in scientific inquiry, research, and how you want to use your knowledge to help advance healthcare.
Example I’ve always been fascinated by science and how things work on a molecular level. The intricacies of molecular biology appealed to my curious nature. My goal has always been to utilize my analytical skills to unlock new discoveries that can improve medicine and human lives. I find it extremely rewarding to conduct studies that add to our collective scientific knowledge. Molecular biology allows me to constantly be learning, questioning and illuminating the unknown.
What Technical Skills and Knowledge Make You Qualified For This Role?
This is your chance to highlight specialized expertise Focus on skills listed in the job description like laboratory techniques, data analysis methods, computer programs, and equipment you have experience with
Example: Through my academic studies and previous lab experience, I’ve developed proficiency in key molecular biology techniques like DNA/RNA extraction, PCR, cell fractionation, fluorescence microscopy, and protein purification. My statistical analysis and data modeling skills are also robust from completing complex experiments and studies. In terms of technical knowledge, I have a strong foundation in biochemistry, genetics, immunology, and pharmacology. I’m also an experienced R and Python programmer capable of analyzing large genomic data sets.
How Do You Stay Up-To-Date on Developments in The Field?
Molecular biology is constantly evolving, so remaining curious and proactive are essential. Share resources, activities, and a genuine excitement for learning.
Example: I make a habit of regularly reading scientific publications like Nature, Science, and Cell to learn about the latest research and innovations in molecular biology. I also attend seminars and conferences whenever possible. Actively engaging in scientific discussions and collaborating with other researchers also keeps me stimulated. I get genuinely excited about major new discoveries or theories in the field. Overall, pursuing knowledge is something I do every single day.
How Would You Explain Our DNA Sequencing Process to Someone Without a Science Background?
Communication and simplification skills are key for molecular scientists. This tests your ability to take a complex technical process and describe it in a way anyone could understand.
Example: I would explain DNA sequencing by breaking it down into three main steps. First, the DNA sample is extracted, purified, and broken into many small fragments. Second, the four DNA chemical bases – A, T, G and C – are identified in each fragment. This is done using lab techniques to cause fluorescent tags to attach to the bases. Third, a DNA sequencer machine detects the fluorescent signals and forms the full sequence by lining up the tagged bases in the correct order. So it’s essentially reading the genetic code letter-by-letter to reveal the sequence. I would also use metaphors or analogies to help explain complicated aspects in a simple way.
How Do You Ensure Consistency and Reproducibility in Your Experiments?
Scientific rigor is mandatory in molecular biology. Employers want to know you follow robust experimental design and documentation procedures.
Example: Consistency begins with utilizing positive and negative controls and running multiple replications of each trial. I randomize samples whenever possible and ensure variables remain constant across trials. My lab notes are extremely detailed regarding materials, methods, equipment settings, and environmental conditions. Before publishing results, I verify that findings can be reliably reproduced. If any inconsistencies arise, I thoroughly review procedures to identify and correct sources of variation, whether technical or human-caused. Maintaining scientific integrity is critical.
How Do You Prioritize Tasks and Manage Your Time When You Have Multiple Experiments Running?
Time and project management abilities are sought after. Discuss tools and systems you use to stay focused when juggling competing priorities.
Example: When balancing multiple experiments, I first use project management software to map out timelines, milestones, and dependencies for each project. This allows me to identify critical deadlines and potential bottlenecks. Daily to-do lists keep me on track with immediate priorities. For efficiency, I block off dedicated time for activities like documentation, data analysis, and sample prep. If an unexpected delay arises with one experiment, I reassess timelines and adjust my schedule accordingly. I also meet regularly with my supervisor to review priorities and progress. Proactive communication and planning are essential.
Tell Me About a Time You Failed to Get the Results You Expected. How Did You Respond?
Things won’t always go according to plan during complex research, so employers want to know you can critically assess issues and pivot effectively. Demonstrate perseverance and analytical thinking.
Example: During one long-term experiment, we unexpectedly observed decreasing protein expression across trials instead of the hypothesized increase. My initial data analysis didn’t uncover any errors. Rather than getting discouraged, I took a step back and started methodically evaluating each variable. This included reviewing lab protocols, equipment quality testing, environmental conditions, and statistical calculations. It turned out that the baseline cell culture was contaminated. By systematically working through potential causes, I identified the source of the aberrant results. While it delayed things, I learned the importance of thoroughly examining all factors to explain anomalies.
Describe Your Research Ethics Regarding Issues Like Animal Testing or Conflicts of Interest.
Research integrity and ethics are paramount in this role. Share examples that demonstrate your standards and commitment to science ethics policies.
Example: I adhere strictly to ethical guidelines like informed consent, privacy, and responsible data management. When human subjects are involved, protocols must ensure voluntary participation, confidentiality, and complete transparency regarding risks. With animal testing, I only conduct studies that follow humane and minimally invasive practices. I’d refuse any requests to influence, falsify or omit data. Being beholden to the scientific method and facts is critical, so any perceived conflicts of interest or pressures must be avoided or immediately reported. Overall, maintaining ethical standards preserves scientific validity and the public’s trust.
Where Do You See Your Career in 5 Years?
This reveals your ambition and interests. While describing a leadership or specialized role, focus on how you want to apply your expanding molecular biology expertise.
Example: In 5 years, I hope to be leading a prolific research team engaged in cutting-edge discoveries. I aim to continue expanding my technical knowledge while also mentoring junior scientists. My goal is to spearhead projects exploring our hypotheses on targeting molecular pathways in cancer treatments. I want to ensure rigorous experiments so our results can inform future drug development or clinical trials. Making meaningful scientific contributions that improve patient outcomes motivates me for the long-term.
Why Are You Interested in This Role and Our Organization?
Closing questions invite you to share why you’re a great culture fit. Discuss how the role aligns with your skills, values, and aspirations.
Example: Firstly, this role focuses on exactly the kind of molecular biology research I’m most passionate about. Your organization’s focus on genetics in infectious disease aligns with my interests in leveraging knowledge to improve health outcomes.
