If you are an aspiring GIS Technician, you might want to know what kind of interview questions you might face during the hiring process.
Here are the top 20 GIS Technician interview questions and their answers:
1. What is GIS?
GIS is a computer-based system used to capture, store, manipulate, analyze, and display geographic data. It is created to solve complex problems about geographic locations and spatial relationships
2. What is the role of a GIS Technician?
A GIS Technician is responsible for collecting, verifying, and maintaining geospatial data. They also assist in creating maps and data analysis.
3. What programming languages do you know?
GIS Technician requires programming skills in order to automate workflows and make repetitive tasks more efficient. Common programming languages to know include Python, R, SQL, and JavaScript.
4. What experience do you have working with GIS software?
Employers want to know you have real-world experience working in the GIS field. Explain the software programs you have experience with and how you’ve used the software and the data to solve real-world problems.
5. How do you manage large amounts of data used for mapping projects?
