Agricultural Laboratory Technician Interview Questions
Describe your experience with preparing and processing agricultural samples for analysis.

Sample answer to the question

I have some experience with preparing and processing agricultural samples for analysis. In my previous role as a research assistant, I was responsible for collecting soil and plant samples from different agricultural sites. I would carefully label and package the samples before bringing them to the laboratory for analysis. Once in the lab, I would follow the established protocols for sample preparation, which involved measuring and weighing the samples, homogenizing them, and extracting the desired compounds. I would also assist in running basic tests and experiments on the samples, such as pH testing or nutrient analysis. Throughout the process, I would ensure accurate record-keeping and documentation of all steps and results.
