In this section, we’ll review the various interview questions that might be asked during a Research Scientist interview at Eurofins Scientific. The interview process will likely assess your technical expertise, problem-solving abilities, and interpersonal skills. Be prepared to discuss your research experience, methodologies, and how you handle challenges in a laboratory setting.

Technical Expertise

1. Can you explain the principle behind High-Performance Liquid Chromatography (HPLC) and its applications?

Understanding HPLC is crucial for many research roles, and interviewers will want to gauge your technical knowledge in this area.

How to Answer

Discuss the fundamental principles of HPLC, including its components and how it separates compounds based on their interactions with the stationary and mobile phases.

Example

“HPLC operates on the principle of separating components in a mixture based on their affinity to the stationary phase versus the mobile phase. It’s widely used in pharmaceuticals for purity testing and quantifying active ingredients in formulations.”

2. What experience do you have with protein purification techniques?

This question assesses your hands-on experience with essential laboratory techniques.

How to Answer

Detail specific techniques you have used, such as affinity chromatography or ion exchange, and the context in which you applied them.

Example

“I have extensive experience with protein purification, particularly using affinity chromatography. In my last project, I successfully isolated a recombinant protein, achieving over 90% purity, which was critical for subsequent functional assays.”

3. Describe a challenging experiment you conducted and how you overcame the obstacles.

Interviewers want to see your problem-solving skills in action.

How to Answer

Outline the experiment, the challenges faced, and the steps you took to resolve them.

Example

“I was tasked with optimizing a PCR protocol that consistently failed. After reviewing the literature, I adjusted the annealing temperature and reagent concentrations, which ultimately led to successful amplification of the target DNA.”

4. How do you ensure compliance with Good Laboratory Practices (GLP)?

This question evaluates your understanding of regulatory standards in a lab environment.

How to Answer

Discuss your approach to maintaining GLP, including documentation, training, and adherence to protocols.

Example

“I ensure compliance with GLP by meticulously documenting all procedures and results, conducting regular training sessions for team members, and performing routine audits of our lab practices to identify areas for improvement.”

5. Can you explain the difference between accuracy and precision in scientific measurements?

This fundamental concept is critical in research and experimentation.

How to Answer

Define both terms clearly and provide examples to illustrate the difference.

Example

“Accuracy refers to how close a measurement is to the true value, while precision indicates the reproducibility of measurements. For instance, if I measure a known standard multiple times and get consistent results, that’s precision; if those results are close to the actual value, that’s accuracy.”

Behavioral Questions

1. Tell me about a time you had a difficult working relationship with a colleague.

This question assesses your interpersonal skills and conflict resolution abilities.

How to Answer

Describe the situation, your approach to resolving the conflict, and the outcome.
