Literally just leetcode. Frankly, it’s amazing how little software engineers invest in this. You can find people on Fiverr who will tutor you on competitive programming for $20 an hour. Hire them for 3-4 hours a week and do it for 6 months. That would be a ~$1000 expense and most people see at least a 30-40k bump in yearly salary when they go from nonfaang to fb/google.
