If you want to become more familiar with Dynamics 365, my suggestion would be to download a trial version of the product. This can be found here.
Dynamics is moving at a fast pace and it’s important to keep up-to-date with the latest features and functionalities.
If your company doesn’t support Dynamics 365, I would definitely recommend downloading the trial version, especially if you wish to purse a career in this area.
Worth noting, the trial edition may not contain all features a full edition would, but remember, it is a trial and it’s just as beneficial for exposure to Dynamics 365.
