As per suggestion I am making my first post, the interview post. I have found several and/or derived several solutions from the posts on this site. I plan on using this forum for a variety of related topics, but right now I am going to post my first issue I can not solve in a following post.
Gotta keep them subject lines appropriate. Believe or not this is like only the third or fourth forum I actually post in.
Welcome to the community forums @ouomediago1170 !
The best way to start is to ask and try to help other into the forums so you are in the right path.
As you can imagine, you'll find information on StackExchange too and you can start diving into the https://devdocs.magento.com/ not only for learning but to correct and improve the docs.
We can't forget the powerful User Guide: https://docs.magento.com/user-guide/getting-started.html.
Another recomendation could be to be aware of Magento issues on Github: https://github.com/magento/magento2/issues (if you are technical, of course).
Also, you should read this post: https://community.magento.com/t5/Welcome-to-the-Magento-Community/Start-here-and-hello-from-me/m-p/5... (in particular the guidelines) and if you are not sure about how to use the forum you can read the FAQ: https://community.magento.com/t5/help/faqpage.
If you need information related with GDPR, you should check this: https://community.magento.com/t5/help/faqpage/title/gdpr
Last but not least, you'll need to get your hands dirty with the platform.
