Please explain how you approach problem-solving when an experiment does not produce expected results.

Sample answer to the question

When an experiment doesn't yield the expected results, my initial step is to review the experiment's design and methodology, cross-checking with existing literature to identify any deviations or errors. I would then discuss the results with my peers for their insights. If we're still stumped, I might rerun the experiment or adjust the parameters based on our collective expertise.

A more solid answer

When an experiment returns unexpected results, I begin by meticulously reviewing all experimental steps and reexamine the data using advanced statistical tools for any anomalies. I also consult current literature to guide my reevaluation. Then, I brainstorm with my team to generate alternative hypotheses. Depending on team input, we may either modify the experiment or consider alternative methods. This collaboration often brings new perspectives that are critical for moving forward in our research.

Why this is a more solid answer:

The solid answer improves upon the basic by incorporating a detailed approach including statistical tools, literature review, and team brainstorming, aligning well with critical thinking, experimental design, and collaboration. However, it could still benefit from expressing time management skills, adaptability to technologies, and how the individual addresses sharing of unexpected findings with a wider audience.

An exceptional answer

When faced with unexpected results, my approach is systematic. Firstly, I conduct a thorough audit of the procedure, data collection methods, and preliminary analysis, utilizing robust statistical software. Recognizing that experiments can sometimes fail due to unforeseen variables, I adapt analytical models as needed. I also engage in comprehensive literature searches to ensure alignment with existing research while staying open to novel interpretations. I facilitate cross-disciplinary team discussions to reevaluate hypotheses and methodologies. If warranted, we redesign the experiment iteratively, involving technological advancements if applicable. Regular team meetings and clear communication channels allow us to efficiently manage our time and resources. Unexpected results are meticulously documented and often communicated through internal reports or discussions at seminars, fostering a research environment that values transparency and learning from every outcome.

Why this is an exceptional answer:

The exceptional answer goes beyond the solid response by demonstrating a strategic and collaborative process, engagement with literature, openness to new technologies, and a proactive communication strategy with the research community. It reflects all evaluation areas and responsibilities outlined in the job description, such as critical thinking, statistical analysis, experimental design, teamwork, time management, and adaptability.

How to prepare for this question

Prepare by formulating a structured approach based on the scientific method and emphasize experiences from past research where you effectively managed unexpected outcomes. Reflect on how you utilized statistical tools and adapted methods.
Familiarize yourself with recent literature and developments in your field of research, and be ready to discuss how you stay updated and integrate new findings into your experimental designs.
Recall instances where collaboration with your peers led to problem-solving breakthroughs and describe your contribution to fostering teamwork in those situations.
Think about how you've communicated complex results, both expected and unexpected, to different audiences and how that contributes to your role as an effective communicator in the scientific community.
