Coinbase runs a practical loop — you build a small working service — alongside medium DSA and a design round on order books, ledgers and idempotency.
Across the 15 questions on this page, the weight sits on these patterns:
This sheet collects 15 Coinbase interview questions, grouped into 8 patterns. They are questions reported as actually asked in Coinbase interviews, and each one carries how recently it was reported so you can practise the current set first.
Trie, Design, Binary Search come first — the patterns on this page are ordered by how often Coinbase leans on them, so working top-down spends your time where the interview actually is. The full order is Trie, Design, Binary Search, Simulation, Dynamic Programming, Hash Table.
At roughly 25 minutes per problem — reading it, solving it and writing the approach down — 15 problems is about 6 hours, or 1 weeks at ten hours a week. Most people do not need all of it: the first two or three patterns cover the majority of what gets asked.

Yes — tick a problem on this page and it stays ticked. The counts per pattern update as you go, so you can see which of Coinbase's topics you have actually covered rather than guessing.
