You may be asked to pull together a 90 day plan as part of your job interviews that is often used as an assessment tool OR you may be asked to pull together one before you start in your new role. If not asked, I still suggest that you pull together one as it will help you structure your first meeting with your new manager and you will establish your objectives easiky this way and avoid any overthinking.
You can watch a fulll video on YouTube.
This is a 90 day plan tempate I suggest everyone completes and agree with their manager when they start in their new roles. It will simply help you be clear as to what is expected from you and help you be less worried about any probationary period. Book a 1:1 with me if you would like us to complete it together (work coach on demand option).
