Ask HN: Starting as a junior data engineer tips?

hello hacker news

i am starting soon remotely as a junior data engineer at a health tech company. i have some experience in this kind of data stuff but not in the specific technologies of the company.

it's my first real job and i have some questions if anyone more experienced would be able to pitch in?

what should i be on the look out for, and how can i prepare? for my long term career, what are the options? should i stay here a while or move on after a time for more $? im not sure what the roadmaps look like but i would appreciate any advice from people with some time in the world already.
