Technical Skills & Experience

• 6. Can you explain a complex microbiological technique you have used in the past?
  - In one of my research projects, I used the polymerase chain reaction (PCR) technique to amplify and detect a specific DNA sequence in a sample. This involved setting up the reaction, running the gel electrophoresis, and analyzing the results.
• 7. How do you handle unexpected results in your experiments?
  - I first assess the validity of my procedures and techniques. If they are correct, I review the samples and re-run the experiment if necessary. I also consult with fellow colleagues or supervisors to troubleshoot and determine the root cause of the unexpected results.
• 8. Can you give an example of a project where you had to collaborate with a team?
  - During my internship, I worked with a team of scientists to study the antimicrobial properties of a plant extract. We divided the tasks among ourselves and regularly communicated to share our findings and discuss our results. This collaboration ultimately led to a successful publication in a scientific journal.
• 9. How do you ensure the proper disposal of hazardous materials in the laboratory?
  - I am well-versed in the protocols for safely storing, handling, and disposing of hazardous materials in a laboratory. I regularly review and follow these protocols to ensure the safety of myself and my colleagues.
• 10. Have you encountered any challenges in your previous research projects? How did you overcome them?
  - In one of my projects, there was limited availability of a critical reagent that delayed our timeline. To overcome this challenge, I researched alternative methods and successfully developed a modified protocol that yielded similar results.

Behavioral Questions

• 11. Can you tell about a time when you had to take a lead on a project?
  - During my undergraduate studies, I was chosen to lead a group project on studying the microbial diversity in different soil samples. I delegated tasks, monitored progress, and coordinated with our professor for guidance and feedback. This project received a high grade and increased my confidence in my leadership abilities.
• 12. How do you handle conflicts in a team setting?
  - I believe in open and honest communication to resolve conflicts. I listen to all parties involved, understand their perspectives, and try to find a mutually beneficial solution. I have successfully used this approach in my team projects and have been able to maintain a positive working relationship with my colleagues.
• 13. Can you describe a time when you had to adapt to a new laboratory procedure or technique?
  - During my internship, I had to work on an automated laboratory instrument that I had never used before. I quickly familiarized myself with the instrument by reading the manual and consulting with my supervisor. I was able to successfully perform experiments and generate accurate results.
• 14. How do you prioritize and manage your tasks when working on multiple projects?
  - I start by making a list of all my tasks and prioritize them based on their deadlines and importance. I then create a schedule and work on one task at a time, giving my full attention to each. I also regularly review and update my schedule to ensure all tasks are completed on time.
• 15. How do you stay motivated and productive during slow periods?
  - During slow periods, I use the time to expand my knowledge and skills by reading scientific articles, attending workshops, or learning new techniques. This keeps me motivated and helps me become more productive when busier periods come around.

Situational Questions

• 16. How would you handle a situation where you discover contamination in one of your experiments?
  - I would immediately stop the experiment and inform my supervisor. I would then thoroughly clean and decontaminate the area and equipment, and repeat the experiment using a new set of materials. I would also take measures to prevent future contamination by reviewing my procedures and using appropriate controls.
• 17. How would you handle a situation where you need to meet a tight deadline for a project?
  - I would first prioritize my tasks and create a schedule to ensure all necessary steps are completed on time. I would also communicate with my team if assistance is needed and work efficiently to meet the deadline. In case of any challenges, I would promptly communicate with my supervisor to discuss potential solutions.
• 18. How would you handle disagreements with a supervisor or team leader?
  - I would calmly communicate my concerns and try to understand their perspective. I would also present any additional information or evidence to support my viewpoint. If the disagreement cannot be resolved, I would seek guidance from a trusted colleague or human resources department.
• 19. How would you handle a situation where you observe a fellow colleague not following proper safety protocols in the laboratory?
  - I would first remind my colleague of the safety protocols and offer assistance if needed. If the behavior continues, I would notify the supervisor or safety officer to ensure the safety of everyone in the laboratory.
• 20. How would you handle a situation where a sample or experiment is not yielding the expected results?
