Some of my tasks included isolation and identification of pathogenic microorganisms, and conducting antimicrobial susceptibility tests. I am also familiar with proper handling and storage of different types of microorganisms.

Behavioral Questions

• 11. Can you share a time when you had to troubleshoot an issue in the lab?
  During my internship, a crucial piece of equipment malfunctioned during an experiment. To troubleshoot, I referred to the manual and colleague knowledge, and eventually discovered a faulty connection. I was able to fix the issue and was commended by my supervisor for my quick thinking and problem-solving skills.
• 12. How do you handle conflicting viewpoints or opinions within a team?
  In my previous research project, there were different approaches suggested by team members for our experimental design. I listened to everyone's ideas and concerns, and facilitated a discussion which led to a compromise that addressed all viewpoints and ultimately resulted in successful outcomes.
• 13. Can you describe a time when you had to work under pressure and how did you handle it?
  During a lab experiment, our team was running out of time to complete the task within the designated hours. I kept a cool head and efficiently delegated tasks to team members, ensuring proper documentation and adherence to protocols. We were able to complete the experiment on time and obtain accurate results, which received praise from our supervisor.
• 14. How do you stay organized and manage multiple projects simultaneously?
  During my academic studies, I had to balance coursework, lab work, and a research project. To manage my time effectively, I created a weekly schedule and made a to-do list for each day, prioritizing tasks based on deadlines and complexity. This helped me stay organized and on track with all my responsibilities.
• 15. Have you ever made a mistake in the lab? How did you handle it?
  In one instance, I accidentally used the wrong dilution factor for a bacterial culture, which skewed our results. I immediately informed my supervisor, and we repeated the experiment with the correct dilution, leading to accurate findings. I learned the importance of double-checking all calculations and communicating any errors promptly.

Situational Questions

• 16. If a colleague was struggling with a protocol or experiment, how would you assist them?
  I would first offer to review the protocol with them and address any questions or concerns they have. If they continue to face difficulties, I would suggest reaching out to our supervisor for additional support or guidance.
• 17. Can you give an example of a time when you had to handle an unexpected issue in the lab?
  During a bacterial culture, our incubator unexpectedly malfunctioned and reached a temperature higher than intended, potentially affecting our results. I immediately notified my supervisor and suggested restarting the experiment with new cultures to ensure accuracy.
• 18. How would you prioritize tasks if you had multiple experiments running simultaneously with tight deadlines?
  I would first consult with my supervisor to determine which experiments are most critical and prioritize accordingly. I would also break down each experiment into smaller tasks and allocate time accordingly to ensure all experiments are completed accurately and on time.
• 19. If you were tasked with presenting research findings to a non-scientific audience, how would you approach the presentation?
  I would first break down complex scientific concepts into simpler terms that can be easily understood. I would also use visual aids, such as charts and diagrams, to help explain the data and findings. I would practice the presentation beforehand to ensure the information is conveyed clearly and concisely.
• 20. How do you handle conflicts with coworkers or supervisors?
  I believe communication is key in resolving conflicts. If I have a disagreement with a coworker or supervisor, I would calmly and respectfully express my concerns and listen to their perspective.
