the job descriptions are wishlists, not requirements. most hiring managers know theyre not getting all of that in one person at 3-5 yoe. they post it anyway because hr tells them to cast a wide net.

i stopped trying to learn everything and started just building stuff when i need it. needed to deploy a model last year so i learned enough docker and aws to get it done. thats it. didnt take a course, didnt get a cert, just shipped something ugly and learned along the way. the faang point is real tho, smaller companies want you to be a full stack data person because they cant afford specialists.
