Your orientation you will arrive, you will have your picture taken by AP for your badge, you will neet with HR and the training specialist. You will spend your first day doing a lot of basic knowledge training (how to use a pallet jack, how to lift a box correctly/safely, etc.) and filling out paperwork that needs to be done.
If its the new process (should be) then the manager you are under will come and meet you and take you on a quick tour of your department so that when you come in for your second day, you will know where to go to be with your team and attend your teams startup meeting.
Its a super chill day, just make sure you keep in mind hooded clothing is not allowed so if you want to bring something to keep warm (advised if you live in a colder are) make sure it doesnt have a hood.
