Vendor terminology is often different (tagged VLANs vs trunking, etc.) but, in general, it is close enough that an experienced person can figure it out with a bit of googling. I've built networks with Cisco, Mikrotik, Aruba/HP, custom Linux routers, and others. Mikrotik VLANs are a bit weird, for sure.
In today's world, is generally easy to get things to communicate. It's not 30 years ago and nobody is running DECnet, Appletalk, or IPX.
Networking can be complex. Standards allow interoperability but they do not magically make everything work with no configuration.
