First job I has as a developer was for a PHP role. I didn't know shit about PHP. Did a small project at school at a point and it was all the experience I had. Lied on resume, got asked some basic questions that where true for all programming languages. Got the job, learned PHP while working.
Can confirm, just lie, worst case scenario you just end up wasting some recruiter's time.
I was using Manjaro until the day my install started giving me problems.with dependencies and duplicated packages (?), so I went with Fedora and it's been smooth so far.
In the old days I used Firefox exclusively, until my work started only supporting chrome so I kinda went with it and switched. Out of habit I continued until a couple of years ago, that I went full Firefox again and I remembered why I loved it.
Granted, you are now a rock
