Learning Linux was probably the very best thing for my career.
The fact that I use Linux as my primary OS has been a positive in almost every interview I’ve been in as the interviewee. Linux has been used everywhere I’ve been, and that represents a huge amount of upskilling they can skip.
As an interviewer, I’d say that developers who use Linux generally understand their development stack better.
This has been my experience as well.
It doesn’t help that, prior to 2023 (I believe), Microsoft’s OpenSSH fork simply did not recognize ProxyJump. I administered a server behind a bastion, which meant every Mac and Linux user could
ssh
in. Windows users had to use some strange program like PuTTy.
