Answer 1

SSH stands for Secure SHell, a protocol for remote connections used by all Linux and Unix machines and their standard way of running commands from remote machines - like a workstation running stuff in a server.
And it provides a secure connection by use of encryption and, optionally, certificates for authentication.
It's definitely not new and not necessarily related to hacking. But it's absolutely necessary if you want to do sysadmin in Linux or Unix boxes or develop code for that.

About the protocol:

About OpenSSH, by far the most used SSH software:

For developers, what really matters is the libraries for SSH. For example, Paramiko - the must learn SSH library for Python:

Answer 2

As i read on internet this is protocol used to share data(like web page), so this company use it, if you wanna work for them learn it.
I dont know how offten this is used, but learning something new in programming is always good thing to do.
If thay suggest you this resourse follow it, probably they found it helpfull so they recommend it.
