What will my first day look like?

Im going to join potentially this summer, like before summer actually. Im thinking may / june. So im going to hypothetically assume id be the only new person there at the gym. I probably wont but assuming i am, im curious, what will happen?

Will the coach announce to everyone im new and to go easy on me ?

Will i be taken to the side while everyone else trains and learn the basics with someone the coach chooses and he says “show him the ropes”?

Will i be thrown straight into the deep end?

How will it work, from the minute i walk into the gym, what will they do with me to assure im taken care of?
