Your first week at a new job, watch who helps without being asked. Stick close to them.

Every workplace has a map that nobody prints. In the first week you cannot tell who is good at the job, but you can tell who notices a new person struggling and crosses the room about it. That instinct is usually attached to the people worth learning from and worth being near when something goes wrong. The ones who enjoy watching you fail are identifiable in the same week.

Pay attention to that in your first few shifts and then put yourself next to those people. Ask them your questions rather than guessing. Once you know the job, be the one who crosses the room for the next new person.
