A chemistry lab assistant interview is your chance to show that you’ve polished these skills to a shine. To help you get ready, we’ve listed chemistry lab assistant questions and answers that will help you figure out what you want to say during an interview.

Are you familiar with the proper handling and storage of chemicals?

The interviewer may ask this question to assess your knowledge of safety procedures in the lab. Highlight your understanding of how to handle and store chemicals safely by describing a time you encountered a chemical spill or other dangerous situation and handled it correctly.

Example: “I am very familiar with proper handling and storage of chemicals because I have worked in labs where we had to do both ourselves. In my last position, I was working on an experiment when one of my colleagues spilled some acid onto the floor. We immediately stopped what we were doing and cleaned up the spill according to our facility’s protocol for hazardous spills. After that, we resumed work on our experiments.”

What are some of the most important skills for a chemistry lab assistant to have?

Employers ask this question to make sure you have the skills necessary for the job. They want someone who is organized, detail-oriented and able to work independently. When answering this question, list some of the most important skills that a chemistry lab assistant should possess. Explain why these are important in your answer.

Example: “The two most important skills for a chemistry lab assistant are organization and attention to detail. In this role, I would be working with chemicals and equipment, so it’s important that I am careful when handling them. It’s also important that I keep detailed records of all experiments and procedures I perform. This helps ensure that everything gets done correctly.”

How would you react if you noticed another lab assistant making a mistake while conducting an experiment?

Employers ask this question to make sure you have the ability to work as part of a team and communicate with your colleagues. Show that you can be honest, but also tactful when addressing mistakes in the lab.

Example: “If I noticed another lab assistant making a mistake while conducting an experiment, I would first try to correct them without drawing attention from others in the room. If they didn’t notice their mistake after my initial correction, I would politely approach them again and explain how what they’re doing is incorrect. I would do my best to remain calm and respectful so that I don’t embarrass or offend them.”

What is your experience working with hazardous materials?

Employers may ask this question to make sure you have the experience working with dangerous chemicals and materials. They want to know that you are familiar with handling these substances safely. In your answer, share a specific example of how you worked with hazardous materials in the past. Explain what steps you took to ensure safety while completing your tasks.

Example: “In my previous role as a lab assistant, I was responsible for disposing of all hazardous waste. This included any leftover chemicals or materials from experiments. Before disposing of anything, I always triple-checked that it was safe to throw away. If there were any questions about whether something could be thrown out, I would contact my supervisor for advice.”

Provide an example of a time when you had to multitask in order to complete your duties in a timely manner.

When answering this question, it can be helpful to provide an example of a time when you had multiple responsibilities and how you managed them. This can show the interviewer that you are capable of handling multiple tasks at once and can help them understand your thought process in doing so.

Example: “In my previous role as a lab assistant, I was responsible for helping students with their experiments while also assisting the lead chemist with various tasks throughout the day. One day, we were running low on supplies and needed to order more before continuing our work. I helped the lead chemist place the order while also completing other tasks such as cleaning up spills and organizing equipment.”

If a lab accident occurred and you weren’t sure how to handle it, how would you seek guidance from your supervisor?

An interviewer may ask this question to assess your ability to seek guidance from a supervisor when you need it. Use your answer to show that you can be proactive and confident in your decision-making skills, even if you aren’t sure how to handle an unexpected situation.

Example: “If I wasn’t sure what to do during an accident, I would first try to solve the problem myself by looking up information on my phone or asking other lab assistants for help. If I still needed more guidance, I would approach my supervisor immediately so they could provide me with additional support. I would also make sure to document the incident in case there were any safety concerns later on.”

What would you do if you noticed another lab assistant stealing supplies or equipment?

Employers ask this question to make sure you can follow the rules and regulations of their facility. They want to know that you will report any suspicious activity, even if it’s from a colleague. In your answer, explain how you would handle the situation by reporting the lab assistant to your supervisor or manager.

Example: “If I noticed another lab assistant stealing supplies or equipment, I would immediately report them to my supervisor or manager. I would also write down all of the details in case they needed to investigate further. If I saw someone take something without permission, I would assume they were taking it for personal use and not for research purposes. However, I would still report it so we could get rid of the items before anyone used them.”

How well do you pay attention to detail?

Attention to detail is an important skill for a chemistry lab assistant. Employers ask this question to make sure you have the ability to notice small details and ensure that you’re not going to make any mistakes in their lab. When answering this question, try to show your interviewer that you can pay attention to detail by giving them examples of how you’ve done so in the past.

Example: “I am very good at paying attention to detail. In my last job as a lab technician, I was responsible for making sure all of our equipment was clean and ready to use each day. This required me to check each piece of equipment thoroughly before using it. If there were any issues with the equipment, I would fix it or replace it immediately.”

Do you have experience using computer-based systems to record data and track experiments?

The interviewer may ask this question to learn more about your computer skills and how you use them in the lab. If you have experience using a specific system, share that information with the interviewer. If you don’t have experience using a particular system, explain what other systems you’re familiar with and why they are similar or different from the one you haven’t used.

Example: “I’ve worked in labs where we used both Microsoft OneNote and Evernote for recording data and tracking experiments. I find both of these programs easy to use and helpful when it comes to organizing my notes and keeping track of important details. However, I prefer Evernote because it allows me to access my notes on any device.”

When performing experiments, are there any safety procedures that you feel are essential to follow?

Interviewers may ask this question to see if you understand the importance of following safety procedures in a chemistry lab. They want to make sure that you are committed to keeping yourself and others safe while working in their facility.
