I think everyone’s advice here is good, I also want to throw on your radar that with your background you can also try targeting Applied Scientist roles instead of Data Science directly e.g. https://www.amazon.jobs/en/landing_pages/ops-tech-applied-science https://www.amazon.jobs/en/landing_pages/ops-tech-applied-sc... Generally the highest value for your background will be Python (do a bit of leetcode), Pandas and Sklearn. PyTorch would also compliment your existing skill set. A lot of the other stuff you can just learn on the job like cloud, dev ops etc. it all differs by where you work. It’s also the shiniest stuff that you can get distracted by and waste time on for less value.
