I’m interviewing for a software dev job currently (it’s in the initial stages). If things work out, I’d absolutely prefer a work laptop with Linux installed (I personally use PopOS but any distro will do), a Mac will be second choice, but I absolutely cannot tolerate Windows, I abhor it, I hate it… (If all computers left on earth have Windows I’d either quit this field or just quit Earth).
Sometimes it’s possible to tell if they use Windows or not, for example, jobs with dotnet/C# are most likely using windows, but not in my case.
Anyways, is it too weird to ask what kind of laptop they provide to their employees? And to also specifically ask for a Linux (or anything but windows) work laptop?
A job interview isn’t just for the company to find out if you are a good hire for them. It’s also for you to find out if the company is a good employer for you.
So yes, ask away. And if they cannot meet your criteria you just don’t start working there.
Much like with dating, showing you have some standards and aren’t just desperate for the first thing that comes along makes you a lot more attractive. If I was interviewing candidates and one of them respectfully voiced a preference for a certain OS laptop during the interview, I would probably look more favourably on them than someone who didn’t voice a preference, all else being equal.
