Crypto Exchange Order Book Interview Guide
Crypto exchange order book interview guide for centralized venues, liquidity, spreads, order flow, fees, market data, and execution risk.
Candidates comparing crypto order books with traditional limit order book mechanics.
Order book mechanics still apply
Crypto exchange order books have bids, asks, depth, spreads, orders, trades, and market data events. The familiar microstructure ideas still need venue-specific caveats.
Fees and access affect quotes
Maker-taker fees, API limits, latency, account constraints, and venue reliability can change whether an apparent quote is useful for a strategy.
Concrete example
A top-of-book spread may look tight, but available depth can be small. For a larger order, expected execution should include depth and slippage across levels.
Data checks are necessary
Exchange feeds can have outages, sequence gaps, stale books, or symbol differences. Detecting bad state is part of a credible systems or quant answer.
Common mistakes
Candidates often compare only mid prices. Strong answers discuss depth, fees, latency, fill probability, and venue risk before calling something an opportunity.
