I did 2.5 years 100% from home when Covid hit, and then we were 2 days in the office, 3 at home. When I moved south last year we're 3 days in the office and 2 at home, but the work culture being a bit different down here, a lot of people are going in 4-5 days a week regardless. I usually do 4 days in the office. It's a easy commute, and I like the people in the office, for the most part, so it's a pleasant place to be. Plus, being 'new' it's nice to have people around you can ask questions and bounce ideas off without having to bug someone on Teams.
That said, WFH does work quite well, tech like Teams can make it really effective and convenient. For me it's all about having a quiet space where the wife and kids are not a distraction. I've always had a dedicated 'office' room in the house, and I've got a bunch of automotive art and whatnot on the walls. I have a nice vintage wood 'mad men' style desk and big comfy button back leather chair. Dual monitor setup is key for the type of work I do, and a good reliable laser printer/scanner is also important so that doesn't become a slow down on the fair occasions you need to print or scan something. I try to stick to the same schedule too with things like coffee, lunch, etc.
I also think how you present yourself on screen is important, especially in a larger corporate setting, if you're on screen in a sloppy t-shirt, your camera angle sucks, poor lighting, etc, it doesn't help to build the professional presence that you need. Same goes for keeping your camera off all the time....Dress decently, at least the top half, and play around with the camera angle, lighting and all that to make sure you look decent. If you're speaking, look into the camera, my tendency is to look at the screen because that's where the other faces are, but looking into the camera makes you appear more focused and engaged to those on the other side of the screen....It's silly, but small things like that do go a long way to building the impression that you make with people when you're remote.
