Did you bring it up with your manager? How about your colleagues. You can significantly affect your chances by talking about it, making clear that you see this as a major benefit (that doesn't cost the company a dime and, in fact, opens up for saving money on office rent), and highlighting that you can be as productive at home as you can in the office, if that's actually the case of course :) Several of us where I work have been doing this over the past year, and in my last conversation with my manager I got approval for working from home permanently even after the restrictions are pulled back. It's hard to say for sure, but I don't think I would have gotten the same answer if we hadn't been very clear and vocal about our preferences. And of course it helps that the company outperformed its pre-COVID19 projections :)

Interview now while everyone is remote and it’s easier to do versus taking time off when you’re forced back into an office.
