Example answer
“In my previous role at a research facility, I was tasked with preparing samples for two different experiments with overlapping deadlines. I created a timeline that prioritized tasks based on their urgency and began with the samples that required the longest preparation time. By organizing my workload and delegating simpler tasks to junior lab aides, I completed both experiments on time, resulting in successful data collection that contributed to our research goals. This experience taught me the importance of clear communication and effective prioritization.”
