Not sure what it's like now, but before they eased on going to office, we tech stayed at home for first few weeks~months (depending on project).

A lot of the time you won't know what you're supposed to do until the last minute. But essentially you have 3 days of orientation, a few days of nothing (so take this time to complete whatever mandatory courses they give you) and then you either go for training or start the project (for tech, depending on project).

My advice, try to mix around and keep in contact in whatever group they put you in during orientation and/or training (they're likely the same people assigned to the same project). It can ease a lot of the pressure/stress if this is your first time working and if everyone's more or less on the same page.

Also helpful because you can help each other keep yourself in the loop. For some reason, there are multiple group chats and everyone likes to only talk physically in person or in 1 chat group. So if you aren't in that chat group or didn't hear it in person, you'll never know something important until the last minute.
