I would also want to spend time getting to know my coworkers so we can collaborate effectively. I would also like to review any existing reports or data to see what improvements we can make moving forward.”

What would you do if you noticed a decrease in crop yield during your inspection of a farm?

This question can help interviewers understand how you apply your engineering skills to solve problems. Use examples from past experiences where you used your problem-solving and critical thinking skills to find solutions to challenges in the agricultural industry.

Example: “If I noticed a decrease in crop yield during my inspection of a farm, I would first ask the farmer what they observed. Then, I would inspect the crops myself to determine if there are any issues with irrigation or nutrient delivery systems. If everything appears normal, I would then check for pests or disease that may be affecting the crops. In one situation, I inspected a farm where the owner reported a significant drop in crop yield. After inspecting the fields, I found that the irrigation system was not working properly. The system had been damaged by an animal, so I recommended replacing it.”

How well do you know the different types of farm equipment?

The interviewer may ask this question to see if you have experience working with different types of farm equipment. Use your answer to highlight the specific types of farm equipment you’re familiar with and explain how you use them in your work.

Example: “I’ve worked on a variety of farms throughout my career, so I’m quite familiar with many different types of farm equipment. Some of the most common types of farm equipment I’ve used include tractors, harvesters, sprayers and tillers. Each piece of equipment has its own unique functions, but they all help farmers complete their tasks more efficiently. In my last role, I helped design new equipment for one of our clients who was looking for a tractor that could handle both large and small jobs.”

Do you have experience working with livestock?

This question can help the interviewer determine if you have experience working with animals and livestock. If you do, they may ask you to describe a time when you used your skills to solve an issue or challenge in this area. If you don’t have any experience working with livestock, you can talk about how you would approach this type of work.

Example: “I’ve worked with livestock before, but I haven’t had much opportunity to use my engineering skills for this purpose. However, I am familiar with many of the challenges that farmers face when raising livestock. For example, I know that it’s important to provide adequate shelter from extreme weather conditions and predators. In addition, I understand that there are several factors that affect animal health, including nutrition and water quality.”

When is it appropriate to use genetically modified organisms in agriculture?

This question can help interviewers assess your knowledge of the industry and how you apply it to real-world situations. Use examples from your experience to show that you know when GMOs are useful in agriculture and why they’re important.

Example: “GMOs are a great way to introduce beneficial traits into plants, which is especially helpful for crops that have been bred over time to be more aesthetically pleasing than nutritious or resistant to pests. For example, I worked on a project where we used GMO corn to create a variety that was both pest-resistant and high in nutrients. This allowed farmers to grow their own food without having to use pesticides.”

We want to increase production without impacting the environment. How would you do this?

This question is a great way to show your problem-solving skills and ability to work with others. When answering this question, it can be helpful to explain how you would collaborate with other team members to come up with solutions that benefit the environment while increasing production.

Example: “I would first meet with my manager and discuss what we want to achieve in terms of production. Then I would talk to our environmental engineer about ways we could increase production without impacting the environment. For example, if we were looking at increasing corn production, we may look into using more efficient irrigation methods or planting different crops altogether. This would allow us to produce more food for consumers while also protecting the environment.”

Describe your process for testing the quality of soil.

The interviewer may ask you this question to assess your analytical skills and how you apply them to the job. Use examples from your experience that show how you use data to make decisions about soil quality.

Example: “I first test the pH level of the soil, which tells me whether it’s acidic or alkaline. I then conduct a nutrient analysis to determine the levels of nitrogen, phosphorus and potassium in the soil. Finally, I perform a salinity test to see if there are any salts present in the soil. These three tests help me understand the overall health of the soil and what nutrients it needs.”

What makes one type of crop fertilizer better than another?

This question can help the interviewer determine your knowledge of agricultural engineering and how you apply it to a company. Use examples from your experience or education to explain what makes one type of fertilizer better than another, and why that is important for an agricultural engineer.

Example: “There are many factors that make one type of fertilizer better than another. For example, some fertilizers have more nitrogen than others, which helps plants grow. However, if there’s too much nitrogen in the soil, it can actually be harmful to the plant. So, I always consider the amount of nutrients needed by the crop and the current state of the soil when recommending a fertilizer.”

Which is more important: yield or quality?

This question is a test of your knowledge and understanding of the two main objectives in agricultural engineering. It also tests how you prioritize tasks to achieve these goals. Your answer should show that you understand both yield and quality are important, but you can identify which one takes priority when necessary.

Example: “Quality is more important than yield because it determines whether or not the product will be marketable. If the quality is poor, then there’s no point in having a high yield. However, if the quality is good, then we can focus on increasing the yield by using better methods and techniques. For example, I once worked with a client who had a low-quality crop. We increased the quality by implementing new irrigation systems and soil management techniques. This allowed us to increase the yield significantly.”

What do you think is the most important aspect of agricultural engineering?

This question can help the interviewer determine your priorities and how you might approach a project. Your answer can also show what skills you value most in this role. When answering, it can be helpful to mention an aspect of agricultural engineering that you are familiar with or have experience with.

Example: “I think the most important part of agricultural engineering is making sure farmers get the best results from their crops. I’ve worked on several projects where we developed new ways for farmers to increase crop yields while reducing waste. It’s rewarding to see farmers use our designs to make more money.”

How often should farmers rotate their crops?

This question can help interviewers assess your knowledge of agricultural engineering and how it relates to farming. Use examples from your experience as a way to show the interviewer that you know what’s best for farmers when it comes to crop rotation.

Example: “Farmers should rotate their crops at least once every three years, but ideally twice per year. This is because rotating crops helps prevent soil erosion, which in turn prevents pests and diseases from developing on plants. It also allows the soil to rest between planting seasons so nutrients can replenish themselves.”

There is a disease affecting the crops on a farm. What is the first thing you would do to contain the outbreak?

This question is an opportunity to show your problem-solving skills and ability to work under pressure. Your answer should include a step-by-step process of how you would contain the outbreak, including what resources you would use and who you would collaborate with.

Example: “The first thing I would do is assess the situation by looking at the crops that are affected and their locations. Then, I would determine if there is any way to treat the disease or prevent it from spreading. If not, I would quarantine the infected area so no one can enter or leave until the disease runs its course. Afterward, I would remove all traces of the disease and disinfect the area before allowing anyone back in.”
