Honestly, good for you. I switched about a year and a half ago after using Windows literally all my life (well, from when I was 5 years old in primary school anyway).
Never looking back. I now know what a good PC experience is like. One that doesn’t bombard you with ads for its own browser and requests to track you every time it stops in the middle of what you were doing to force an update that only makes your experience worse.
I personally use Nobara on my main PC and OpenSuse on my laptop, but whatever you go with, I wish you a good time. (And know that if you don’t, there’s always a distro out there that will fit your usage better!)
Remember back in school there would always be that one kid who was able to get the teacher talking and going off topic so the class had to do less work?
Basically learn to do that in your interviews. If you’re lucky enough to know the name of your interviewer beforehand, stalk their LinkedIn and try and find something they’re interested in. People love talking about themselves. If you can manage to get your interviewer rambling about something they like, they will come away feeling it was a good interview, and you’ll probably learn a hell of a lot more about what the job is actually like on a day to day basis.
I’ve found that the smaller the company, the higher the success rate doing something like this. Larger companies tend to have a more rigid interview structure or have multiple interviewers at once.
