This list comes from community-sourced LeetCode company lists. It covers coding questions only. It does not tell us how many rounds Coinbase runs, what each round covers, or what it pays, and those change by role, level and team, so we do not list them. Ask your recruiter what each round covers, and check the company's careers page.

Tips for Success at Coinbase
Start with the 12 most reported Coinbase questions, then work down the list.
Mediums are the bulk of the list (67%), so spend most of your time there.
Time yourself: 20 to 30 minutes per medium, then explain your solution out loud as if to an interviewer.
After each problem write down the pattern and the signal that revealed it. Patterns transfer to problems you have not seen.
Pair coding practice with a system design framework and prepared behavioral stories; most loops include more than coding.
