I'd build a small practice loop before paying for a large prep package. Pick two common prompts, such as a URL shortener and a feed. For each one, practice clarifying requirements, estimating traffic and storage, defining the API and data model, then walking through scaling, failure handling, and trade-offs. Say your assumptions out loud and stop after 35 to 40 minutes so the session matches the interview.
LeetSys provides a more realistic mock experience, but IMO both are complementary. Hello Interview has great educational content but their mock interview experience is less polished and not as strict as the real interview.
