CodeWeavers Hiring More Developers to Work on Wine and Valve's Proton

By my experience, it helps a lot to have a handful of patches in Wine already. Doesn't have to be anything especially great, but showing that you can work with the conformance tests (both write them and fix them), create good commits, go through the patch review process, interact constructively with the maintainers can get you a lot of points and make up for a not necessarily perfect interview test.

Do not look for the super-core stuff like user32.dll and ntdll.dll. There is already a lot of folks working there and it's hard to make an improvement if that's your first contribution. But there are a plethora of random forgotten libraries in dlls/ which usually nobody cares about until some application depends on those, and they are quite likely to have a good amount of low hanging fruits. Look for the todos in the tests, for example.

Disclosure: I work for CodeWeavers, but I am not involved in the hiring process.

I applied early last year, and got rejected by a Senior from CodeWeavers but without any insight...

Just:

"The senior reviewed your work and it's a 'no'. However you may want to consider submitting patches to either Wine or Proton. Developers that get patches into either of these projects tend to be sought out and offered developer jobs."

I found it gross, and thought that it was actually an ad to contribute to both Wine and Proton first, and not hire someone.

I know I am not the best C programmer in the world, but I think that if you spend two hours of your time doing a test to have a chance for an interview, you might have a feedback of what was wrong instead of a "nope dude".

The test was composed of two things: 1. reviewing a bad C code and make comments, 2. you have an is an unimplemented string sorting API and you have to provide the implementation, the unit tests, etc.

First time and last time I applied to CodeWeavers.

Are people still playing KSP2? I was one of the few people who were optimistic about it, but then they fired the devs, and the game hasn't been touched in months (despite still being sold for full price on Steam).

that would be impressive since I wouldn't consider the game playable on any OS

Older versions of Office have worked okay for a while now. Newer cloud-reliant ones are just going to break time and time again. On Linux your options basically boil down to O365 for Browser or Libreoffice.
