It’s as if they had two choices:
“we’ll provide clothes but you can bring your own lunch!”; vs
“wear your own clothes and we’ll provide lunch!”
and they chose the weird one not the helpful one.
I am extremely picky about keyboards, screens, and OS configuration as a result of being partially deaf, having poor eyesight, and honestly being a bit of an old stick in the mud. It would be lovely to set aside some space on an old Thinkpad for work tasks. It would be comfortable and easy to isolate and be just like my personal machine.
Instead I get a choice between a MacBook with a fixed alternate key layout or a Windows machine with a locked down bright white wallpaper and a non admin account.
Cheat code for this: ask them if they need any custom tooling. I spent a few hours at a past job on a userscript for their ticketing interface to fix some annoyances. Brownie points for life.
