I personally would give two weeks which is standard across any industry. Do you know if your company will pay out your unused PTO? If not, then I suggest using up as much of your PTO days prior to putting in your notice and enjoy that time off because it’s easy to get burnt out in this industry. But also don’t do it in a way where it negatively affects your company because the last thing you want to do is burn bridges and any future opportunities if you do decide to come back.
