¿What a Gis Analyst do?

First of all, Hello!

I'm making this post to ask you about something that might be elementary: what does a GIS analyst do? I am currently an environmental science technician. I took a remote sensing and GIS course where I learned to use QGIS. During 2022, I participated in a research project where I was asked to georeference different variables from multiple maps to obtain an overview of a situation. Is this the kind of thing done in jobs like this? I also wanted to ask how different the ArcGIS interface is from QGIS. Lately, I've been looking for work, and this is a position I'm considering. At the same time, I'm thinking about learning some SQL and Power BI because I understand they could be complementary for data analysis. Am I correct? If not, what would you recommend I learn? Finally, for job searching, I'm using LinkedIn. Do you think I can find something there? I'm from Argentina, and I don't see many job postings.

Thanks!
