At my current job, our department (DevOps), uses Linux (arch). A couple of devs too (Ubuntu), the rest use a mix of Macs and Windows. The Online versions of Office work just fine, there is Teams, Azure login and even Intune for Linux now.
At my previous job, most of the company used Windows, but the devs were using 90% Linux (Ubuntu), some of them with 2 machines (laptop and workstation with GPU, point cloud stuff). Ah, the good ole days of Ubuntu 16 and Nvidia drivers 🥲
The job before that, a very small company, mostly devs, we were using half Windows, half Linux (mint).
