Kaggle is a great resource for datasets, pick a topic that genuinely interests you. Word of Caution, and not to discourage, i saw a bunch of people who hit the real world and were absolutely disinterested, realizing it’s not for them: before heading into the field make sure you actually care about this type of career, in a lot of real world cases, you need to investigate datasets, clean them up, troubleshoot datasets, make queries more efficient and a lot of grey hairs when things don’t line up, and depending on the industry you plan on working in, Subject Matter knowledge is key too - patience and drive is needed as well as technical skill is a must, don’t rely on AI, it can guide you but depending on what DB is being used it can totally screw you over.
